Many users, including myself, have encountered such a frequent fox browser problem as bookmarks not opening. It consists in the fact that when you click on the “+” button, a new bookmark does not open. Restarting the browser, as a rule, does not give any results, however, there is still a way out of the situation when bookmarks in Mozilla do not open.

There are several troubleshooting scenarios - quick, and long. And now, in order, I will tell about them.

Quick option

The most effective solution, which is usually used to restore a working state of FireFox, is to roll it back to its original state. This function is a built-in feature of the browser, and it is performed in just a few clicks.

1. All installed add-ons will be disabled.
2. The user profile will be recreated, and all settings from the previous profile will be transferred to a special folder, so that in fact you will not lose any saved sites in your favorites, or any other information.

But any changes made to the browser itself (due to which, probably, bookmarks do not open in Mozilla Firefox) will be cancelled.

So, in order to return the browser to its original state, you will need:

1. Run it.
2. Open the main menu by pressing the button on the right side of the toolbar.
3. Click on the question mark icon.
4. Select "Troubleshooting Information".

On the page that opens, you just need to click on the "Clear FireFox" button and confirm the action to be performed. The browser will close and reopen after a while in its standard state - as if it had just been reinstalled.

Important! After the cleanup is done, check the contents of your desktop. A folder should appear on it where all the information from the previous profile will be stored - after all, it will not be good if, due to the fact that your bookmarks do not open in Mozilla Firefox, important data and saved links will be lost.

long option

To fix your problem in the second way, you will not need to return the browser to default settings. Here you will need to arm yourself with patience, and do the same procedure several times.

Based on the experience of Firefox users, the problem can be caused by some installed extension(You can read more about removing plugins). Therefore, if your bookmarks do not open in Mozilla, you will need:

1. Launch browser.
2. Open the main menu of the browser and go to the "add-ons" section.
3. Open the "Extensions" tab and start turning off each of the applications you have installed one by one, restarting the browser and checking the functionality of opening bookmarks.

Advice! First of all, pay attention to extensions that make changes to the browser toolbar. All kinds and other publishers should be checked first.

After the procedures done (it doesn’t matter which of the two described paths you decide to go), the opening function new page should work fine. I hope this article was useful for you, and in the future you will keep track of which extensions are installed in your browser!

Dear friends, there are situations when even the most experienced user needs a hint or a reminder. So it was with me, a situation arose when the work of the usual Firefox put me in a daze.

In fact, this happened before, but now I decided to figure out what the catch is. In general, there are situations when a site (for example, my blog) does not open in the Firefox browser, while it opens in other browsers. Mysticism and nothing more, but such a situation is described even in the manual "Firefox does not work" on the mozilla support website. I decided to put it on my blog as well.

In principle, the problem described above has several solutions. So the reason for the inability to open sites in the Firefox browser may be the prohibition of the firewall, antivirus, etc. The solution in this case is obvious - remove the ban.

If you are connecting to the Internet through a proxy server, then problems may be related to Firefox's proxy settings. Click: Firefox > Preferences > Settings > Advanced > Network- click the "Configure ..." button in the "Connection" section and look at your connection parameters.

In my case, the problem was related to the default IPv6 supported in Firefox. In order to disable it, we type in the address bar: about:config - and press the Enter button. Next, a warning will appear that you must be careful, press the button "I promise that I will be careful!" Next, enter the value in the "Search" field: network.dns.disableIPv6 - and double-click on the found parameter, changing its value to true.

There may also be a problem with the so-called pre-resolution of domain records (DNS Prefetching). In order to disable it, we type in the address bar: about:config - and press the Enter button. Next, a warning will appear that you must be careful, press the button "I promise that I will be careful!" Next, enter the value in the "Search" field: network.dns.disablePrefetch - and double-click on the found parameter, changing its value to true.

And last but not least, clear the cache and cookies of the Firefox browser. To do this, press Ctrl+Shift+Del. In the "Clear" list, select "All". Click "Details" and set the necessary checkboxes. Click the "Clear Now" button.

That's actually all. Thank you for your attention. Good luck!

Py.Sy. there is also a problem with the DNS at the provider and then the browser has nothing to do with it. Here you can try using an alternative DNS from Yandex or Google. Read more, for example.

This article describes issues where Firefox cannot load websites while other web browsers (such as Internet Explorer Safari Epiphany on Gnome or Konqueror on KDE) can. When this happens, Firefox may show an error message Server not found or Connection attempt failed.

• If you see other error messages when you try to browse websites in Firefox, see Websites won't load - Troubleshoot and fix errors.
• If none of the web browsers on your computer can load websites, see Firefox and other browsers cannot load websites.

Internet Security programs are blocking Firefox

If you were able to load websites before the Firefox update, or until your Internet Security program was updated, changed, or replaced with a new one, then your Internet Security program (including firewalls, anti-virus programs, anti-spyware, and more) is probably blocking the connection Firefox to the Internet.

Note: Some Internet Security programs may block Internet access even if they are in the "Disabled" state.

Firefox connection settings

If you are connecting to the Internet through a proxy server that is having connection problems, you will not be able to download websites. To check proxy settings in Firefox.

Good afternoon. Since yesterday, many sites in Firefox have been loading for a very long time - pages are slowly opening. The strange thing is that the site header loads very quickly (by the way, Izcity is a vivid example of this), and then nothing happens for a minute or a half. Then the content of the page falls out at once.

My Internet is fast - 40 megabits. His speed was measured - that's exactly what it is. In Chrome, everything loads much faster. What could it be? How to make Mozilla load pages faster?

Thanks Denis, it really helped that this proxy does not interest me, but you are a genius!!!

Mozilla Firefox needs to be demolished! I had 4 browsers working at the same time. Google Chrome, Yandex, Internet Explorer 11 and Mozilla Firefox. Everything works fine, except for her. And it's not about extensions or hard drives. The browser is just made with crooked handles, that's all!))) Good luck! Well, or, as an option, put an SSD instead of an HDD on the system disk. Everything will work many times faster and this buggy and slow Mozilla Firefox.))

Also, the number of simultaneously open tabs in Mozilla Firefox affects the speed of loading sites. The more of them are open (20-30 or 50 pieces) - the more computer resources the browser consumes and, accordingly, it works slowly and harder, in particular, it slowly loads sites. In this case, you need to reduce the number of simultaneously open tabs to an acceptable level. This is the first reason for the brakes.

The second reason is the extensions (add-ons) in Mazila Firefox. The more installed, the worse for the speed and performance of the browser. Moreover, it may start to slow down the extension, which worked adequately yesterday. Why can this be? Well, for example, the extension silently updated itself to a new version of . Or your browser version has been updated. Or you launched a program on your PC that started to conflict with the extension.
What to do? Get rid of extensions-brakes. At random, disable them one by one and look at the behavior of the browser. Thus, you can find the brake extension and disable or remove it.

Denis | April 6, 2016, 09:51
In the network settings, look to see "No proxy", it helped me. For some reason, I had "Use system proxy settings", I don't know how it changed, I didn't change it myself.

I agree with the user under the nickname "Krynochkin". Here you need to try clearing the cache, maybe this will work. But I clear the cache a little differently. There is a "Journal" button in the browser menu, click on this button. And then go to "Remove recent history". Now opposite "Delete" set the value to "All". And in your case, you need to check the boxes next to: "History of visits and downloads" and "Cache". And then click on "Delete now".

Krynochkin | February 24, 2015, 14:09
You need to clear your browser cache. You can clear the cache in Mozilla Firefox like this. Go to settings. Select the "Advanced" tab. There is an additional tab "Network" - in it, find the "Clear now" button. It should be in the "Cached content" section. It must be pressed - the entire cache will be erased. You can also clear files for offline work (just below the cache, in the same tab).

Internet speed has nothing to do with it. If 40 Mbit / s is fast Internet, then 100 Mbit / s (like mine) - what will the Internet be like? According to my observations, everything affects the page loading speed: the browser (type, version, where it is, what programs still work from the same disk), the state of the system (errors, contamination, bloat), simultaneously occurring processes in the computer, the capabilities of the computer itself (resources ), CPU overheating.

It turns out that Internet speed has the least effect on download speed (although theoretically it affects directly). Some sites tend to take a long time to load, for example, after updating the softpedia site, on the first visit to a computer session, it loads for about two minutes, it does not even load, but everything freezes for this time, and then the page appears at once. I know of several such sites. On other sites (on some), the computer starts to buzz - the processor is warming up.

This is a question from the archives. Adding responses is disabled.

Now let's move on to the Mozilla Firefox browser. This browser is one of the most functional and flexible. By changing the parameters of the browser, you can customize it for yourself, but for this you need to know which parameter is responsible for what. If the setting is incorrect, you risk worsening the browser, but remembering the default values, you can always normalize the browser.

Clearing the browser cache:

1. In the Firefox menu, open "Settings" (Figure 1).

Figure 1. FireFox Menu

2. In the "Advanced" section, select the "Network" tab (Figure 2).

4. In the section " Appearance"Find a theme called "Default" and opposite it click "Enable" (Figure 12).

Figure 12. Appearance

Most simple steps We have done. Now you can perform more complex, but more effective actions. True, if performed incorrectly, this can lead to unfavorable results, so be careful and, just in case, write down the standard values ​​\u200b\u200bof the edited parameters. So let's get started:

1. In the address bar of the browser, enter "about:config" (be sure to enter it manually, when copying the required page will not open) (Figure 13).

Figure 13. Address bar

2. Read the warning and, if you agree, click "I promise I'll be careful!" (Figure 14).

Figure 14. Caution

3. Find the “network.http.pipelining” parameter in the list (indicating this name in the “Filter” line) and set (by clicking on the line of this parameter twice with the left mouse button) the value “true” (Figure 15).

Figure 15. network.http.pipelining

4. Next, we find the “network.http.proxy.pipelining” parameter, for which we also change the value to “true” (Figure 16).

Figure 16. network.http.proxy.pipelining

5. We do the same with the “network.http.pipelining.maxrequests” parameter, only we assign the value “32” to it (Figure 17).

Figure 17. network.http.pipelining.maxrequests

6. Right-click and select "Create", "Integer" from the drop-down list (Figure 18).

Figure 18. Creating a parameter with an integer value

7. Enter the name "nglayout.initialpaint.delay" (Figure 19).

Figure 19. nglayout.initialpaint.delay

8. Enter the value "0" (Figure 20).

Figure 20 Entering a value

Figure 21.network.dns.disableIPv6

10. Next, we give the parameter "content.notify.backoffcount" (if it is not there, then we create it in the same way as we did before) the value "5" (Figure 22).

Figure 22. content.notify.backoffcount

11. We do the same with the “ui.submenuDelay” value (if it does not exist, then we create it), only we assign “0” to it (Figure 23).

Figure 23. ui.submenuDelay

12. And, finally, the parameter "plugin.expose_full_path" (if it is not there, then create it, right-click - Create - Boolean) we give the value "true" (Figure 24).

Figure 24 plugin.expose_full_path

13. Close the settings page, restart the browser.

Thus, we will speed up the loading of Internet pages in the Mozilla Firefox browser.

One of the most common problems with any browser is when web pages refuse to load. Today we will take a closer look at the causes and solutions to the problem when the Mozilla Firefox browser does not load pages.

The inability to load web pages in the Mozilla Firefox browser is a common problem that can be affected by various factors. Below we will look at the most common ones.

Reason 1: no internet connection

The most banal, but also common reason that Mozilla Firefox does not load pages.

First of all, you will need to make sure that your computer has an active internet connection. You can check this by trying to launch any other browser installed on your computer, and then going to any page in it.

In addition, you should check if another program installed on the computer does not take all the speed, for example, any torrent client that this moment downloads files to your computer.

Reason 2: Firefox is blocked by antivirus

A slightly different reason, which may be related to the antivirus installed on your computer, which can block access to the Mozilla Firefox network.

To rule out or confirm this possibility of a problem, you will need to temporarily suspend your antivirus and then check if the pages are loading in Mozilla Firefox. If, as a result of performing these steps, the browser has improved, then you will need to disable network scanning in the antivirus, which, as a rule, provokes the occurrence of such a problem.

Reason 3: changed connection settings

Firefox may not be able to load web pages if the browser was connected to a proxy server that is not currently responding. To check this, click on the browser menu button in the upper right corner. In the menu that appears, go to the section "Settings" .

"Additional" and in subtab "Net" in the block "Compound" click the button "Tune" .

Make sure you have a check mark next to the item "No Proxy" . Make any necessary changes, if necessary, and then save the settings.

Reason 4: Incorrect work of add-ons

Some add-ons, especially those aimed at changing your real IP address, may cause Mozilla Firefox to not load pages. In this case, the only solution is to disable or remove the add-ons that caused this problem.

To do this, click on the browser menu button, and then go to the section "Additions" .

In the left area of ​​the window, go to the tab "Extensions" . The screen will display a list of extensions installed in the browser. Disable or remove the maximum number of add-ons by clicking on the corresponding button to the right of each.

Reason 5: DNS Prefetching is enabled

Mozilla Firefox has the feature enabled by default. "DNS Prefetch" , which is aimed at speeding up the loading of web pages, but in some cases it can lead to crashes in the web browser.

To disable this feature, go to the address bar on the link about:config , and then in the window that appears, click the button "I'm taking the risk!" .

The screen will display a window with hidden settings, in which you will need to right-click in any free area from the parameters and in the displayed context menu go to point "Create" - "Boolean" .

In the window that opens, you will need to enter a name for the setting. Write the following:

network.dns.disablePrefetch

Find the parameter you created and make sure it has a value true . If you see the value false , double-click the parameter to change the value. Close the hidden settings window.

Reason 6: an overabundance of accumulated information

During operation Mozilla browser Firefox collects information such as cache, cookies, and browsing history. Over time, if you do not pay due attention to cleaning your browser, you may experience problems loading web pages.

Reason 7: Incorrect browser operation

If none of the methods described above helped you, you may suspect that your browser is not working properly, which means that the solution in this case is to reinstall Firefox.

First of all, you will need to completely remove the browser from your computer without leaving a single Firefox-related file on your computer.

And after the removal of the browser is completed, you will need to restart your computer, and then proceed to download a fresh distribution kit, which you will later need to run in order to install Firefox on your computer.

This article describes problems where Firefox cannot load websites but other Web browsers (such as Internet Explorer Internet Explorer or Microsoft Edge safari Epiphany on Gnome or Konqueror on KDE) can. When this happens, Firefox may show a Server not found or Unable to connect error message.

• For other error messages that display when you try to view websites in Firefox, see Websites don"t load - troubleshoot and fix error messages .
• If none of the Web browsers on your computer can load websites, Firefox see and other browsers can"t load websites .

Internet Security software blocking Firefox

If you were able to load websites until you updated Firefox or until your internet security software was updated, reconfigured or a new one was added, your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is likely preventing Firefox from connecting to the Internet.

Note: Some Internet security programs can block Internet access even when they are in a "disabled" state.

In general, you should make sure your Internet security software is up-to-date and remove Firefox from your program's list of trusted or recognized programs, then add it back. For instructions on how to configure some programs, see the Configure firewalls so that Firefox can access the Internet article.

Firefox connection settings

If you connect to the Internet through a proxy server that is having connection problems, you will not be able to load websites. To check your connection settings in Firefox :

If you find that changes you make to your Firefox connection settings are not remembered when you restart Firefox, see How to fix preferences that won't save .

IPv6

Firefox supports IPv6 by default, which may cause connection problems on certain systems. To disable IPv6 in Firefox:

DNS Prefetching

Firefox attempts to speed up loading new websites by using DNS Prefetching , which can cause page load errors with some system configurations. To disable DNS Prefetching:

1. type about:config in the address bar and press Enterreturn.
   A warning page may appear. Click I accept the risk!Accept the Risk and Continue to continue to the about:config page.

1. Right-click Hold down the control key while you click in the list of preferences, select New , and then select Boolean .
2. In the Enter the preference name field, enter network.dns.disablePrefetch and click OK .
3. Select true when prompted to set the value and click OK .

Firefox cannot load certain websites

If you find that Firefox can load some websites but not others, first clear your Firefox cookies and cache:

Check for malware

If clearing your cookies and cache did not enable you to load the websites that did not work in Firefox, you should check your computer for malware . Certain types of malware are known to target Firefox and can prevent it from loading various websites:

• If you have an antivirus or Internet security program, update its detections database and do a full scan of your system.
• If you still have problems, follow the instructions in

Fortunately the market software offers a sufficient selection of different browsers. So, in addition to Firefox and Microsoft Edge, you can turn your attention to Chromium-based browsers: Google Chrome, Opera or Vivaldi.

Although all these browsers are written according to the same web standards, the practical application of these standards can vary significantly. If a site looks strange in one browser, you can always try to open it in another.

In this article, we will look at possible ways solving the problem with opening pages on the example of the Mozilla Firefox browser.

Install the latest update

There is a chance that installing a new version of the browser will help solve all the problems that may have arisen in old version. So instead of resetting add-ons and settings, just try to install version 62.0 first.

In the new version of Firefox, you are unlikely to notice any significant changes. However, we still recommend keeping your browser up to date as this avoids many security risks.

Check your computer for viruses

If suddenly you suspect that the problem may lie in a virus, then run the following three programs in turn: the Safety Scanner utility from Microsoft, antivirus program Malwarebytes and antivirus utility Hitman Pro. If one of the programs detects malware, then after removing it, start all three programs again.

However, it is worth clarifying that it is unlikely that malware are the root of the problem in this case. As a rule, if a virus infects a browser, then this is manifested by pop-up advertisements, change start page, redirecting to some other sites or something similar, but not blocking access to certain websites.

Clean up Firefox

As a rule, in most browsers, problems that arise are solved quite in a standard way. However, Firefox offers extremely interesting feature"Clear Firefox", with which you can try to quickly and quickly deal with the problem.

As soon as you click the "Reset Firefox" button, the browser will return "to its default state, while saving important information for you: bookmarks, passwords and open tabs". Besides, this operation will remove the extensions and their saved data.

Firefox stores all of your bookmarks, passwords, search history, web form autofill information, and other data in a dedicated profile folder. After Cleaning Firefox, a new profile folder will be created, into which it will be copied important information from your old profile. At the same time, your old profile will not disappear without a trace. Firefox will save it on your desktop in the Old Firefox data”, so that, in which case, you can restore important information for you. However, it is worth considering that the more old data you restore, the more likely you are to get back something that was the root cause of the problem.

Check extensions and add-ons

A modern product is always missing some features, thanks to which the market for after-sales additions and improvements is actively developing. The most popular of these add-ons are subsequently built into official version product.

Today, there are thousands of add-ons, extensions, and themes for most browsers (with the possible exception of Microsoft Edge). Unfortunately, extensions very often carry a significant number of bugs, as a result of which there are problems with access to sites.

The best way to solve this problem will disable or remove all add-ons, extensions and themes. After that, you need to see if the browser functions normally without them. If the problem is solved in this way, then after that you need to add extensions and themes back one by one to find out which ones negatively affect the work.

Some browsers have a so-called "Safe Mode" which is very similar to Safe Mode. windows mode. If you start the browser in this mode, it will load without any additions and extensions. This move can also solve the problem for a while.

To open Firefox in safe mode, open the settings menu (three vertical lines in the upper right corner) and click the help button. From the menu that appears, select Restart without add-ons. Another way to open this browser in safe mode is to simply hold down Shift key while opening and loading Firefox. Once you've tested the browser without additional extensions, simply close the window and open Firefox normally.

Google Chrome does not have a similar safe mode, however, in this browser you will achieve the same result if you start the window in incognito mode. To do this, simply press the keyboard shortcut Ctrl + Shift + N or click on the three vertical dots in the upper right corner (Settings and Controls Menu) and select "New Incognito Window".

Disabling extensions in Chrome is quite simple and manual. To do this, go to the Settings menu, select "More Tools" > "Extensions". To get started, try clicking the Update button to check if all your extensions are up to date with the latest released versions (note that this button will only appear when Developer Mode is enabled - the slider in the upper right corner). If updating extensions does not help, then remove them all and add one at a time to find out which extension is interfering with normal operation.

Clear the cache

When you visit a website, your browser adds the address of that website to its history and stores a copy of it in the cache. Such data is known as Temporary Internet Files.

The next time you visit the same site, your browser simply loads the saved page, because doing so is much faster than making an Internet request for all the information again. If something is wrong with the cache, then the page may simply not open.

By pressing the key combination Ctrl + F5, you will reload the current page, so that the browser can load it new version. Sometimes this option can help solve the problem.

If this action does not correct the situation, then you can try to delete the entire cache, as well as cookies.

To delete temporary internet files in Firefox, select "Settings" from the browser menu, go to the "Privacy" tab, then click on the "Delete your recent history" option. This action will bring up a pop-up window in which you can choose which period you want to clear the history for. For a more precise choice of what exactly you want to delete, click "Details" - in the drop-down list you can check a number of options from the History of visits to Site settings. First, try deleting just the cache. If this does not help, then delete cookies and all other information.

To do the same in Chrome browser, open the menu by clicking on the "Google Chrome Settings and Controls" button, select " Additional settings”, then go to the item “Delete browsing data”. As with Firefox, you can choose the time period and specific items you want to remove. When you go to the "Advanced" section, you can get rid of data such as passwords, media licenses, and autofill data.

Reinstall browser

Sometimes even deleting all malicious files, disabling extensions and clearing the cache does not solve the problem with the browser. In this case, only a radical solution to the problem can help: you need to delete the browser and all files associated with it, restart the computer, and then install the same browser again.

Unfortunately, due to this action you will lose all your saved passwords, bookmarks, search history and everything that you have not previously saved. Therefore, this step can be considered a last resort in the case when all other tips have been tried and do not help.
