Firefox does not download pages. Firefox does not open pages: home remedies browser. Check computer for viruses

In completely any, even the most ideal program sometimes fails. They can be connected with different reasons. And Mozilla is not an exception to the rules. It can also happen interruptions, errors and bugs appear. Users constantly torments the question - "So how to eliminate these errors?". We will try to answer the most clearly and clearly and clearly.

We will consider the most common mistakes that the system knocks out at that moment when the browser fails. And if not working Mozilla Firefox.then you need to carefully study which error crashes to remove it.

Does not work, or does not start Mozilla: what to do?

We will try to help solve your problem so that she never returned. But before you need to understand, because of what it happens. Therefore, let's consider the most common Mozilla errors.

When you click on the label, the browser does not open

It is difficult to explain why this happens that earlier Firefox opened normally and without any problems, but at some point it stopped reacting and not started at all. The reason can be damaged files, viruses and even system failures.

Let's try to eliminate this problem:

Option 1.Try to restart the computer. In some cases, it helps and performance resumes. If you have already tried this option, and it turned out to be invalid, follow the next instruction.

Option 2. You can try to roll back the data to an earlier version ( this feature Available on Windows 7 and later versions). In most cases, this turns out to be effectively and helps with a similar error. How to do it:


  • Select the recovery point and carry out this operation.
  • After the data rollback is carried out, restart the computer and try to go back to Firefox.

Option 3. Antivirus blocks the work of the browser. Try to disable your security system and start your browser. If it starts, it means it will be necessary to disable the network scanning system so that Mozilla worked fine. But take into account that this can increase the risk of infection with your computer with malicious programs.

Option 4. Need to try to open Firefox in safe mode. And if the browser in it normally start, it means that the case is in some established extensions and additions. In this case, being in this mode, try to turn off all extensions and plugins. And if, later, the launch in the usual mode will be carried out without any problems, then just find and delete the extension that does not allow the program to start.

Browser does not answer

Probably the most common mistake that can occur from users. It may very often be so that when using the program, it suddenly freezes and does not respond to anything, and in the browser header writes: "Does not answer." Let's figure out how to eliminate this error.

Here we will help the Task Manager:


Of course, all data will be lost, and the tabs are closed, but they can be restored by pressing the recovery button, which appears in the browser during the emergency closings of the program.

If aFirefox still does not answer:

This may mean that there are certain problems with the rights of access to the program.


Now try to open the browser again, it should work. If not, only a complete reinstallation will help.

Very slowly slows down when working

A similar problem is found in several cases. Bad specifications Computer, overload of the system, a bunch of garbage in the form of history, cookies and cache, as well as malicious programs.

  1. In the first case, everything is clear. You need to either get a more powerful computing machine, or minimize the number of operational and processor memory consumed by reducing the working processes. Simple words, just remove all unnecessary and almost unnecessary programsthat take too many RAM memory.
  2. In the second case, the Mozilla browser can be buggy if you launched too many tabs and different programs. Moreover, this may happen even on a computer, stuffed with steep components. What needs to be done in this case:

- Close all programs that consume a lot of "RAM".

- Free more memory due to the removal of some unnecessary processes.

- Clean the registry and temporary files using the CCleaner program.

  1. The reason can also be a large amount of garbage that has accumulated in all the time of your work in the web browser. Then you need to do the following:

Well, the problem with viruses is solved, I think it is understandable how. Install any antivirus (if it is not already installed). Run the scan of the entire computer for viruses. And if at the end of the scan, the program will detect them, make their removal. After that, you need to restart the system and you can try to run the browser.

Profile error in Mozilla Firefox

As a rule, a similar error indicates that the profile in the browser was damaged, moved, or removed at all. You can try to restore the data, but it will be easier to create a new profile.

How to do it:


The most universal way - reinstalling;)

If you have tried everything that is listed above, but your problem did not solve, or you have another mistake at all, the solutions of which you did not find in this article, then in this case the perfect version will be a complete reinstalling program of Mozilla Firefox. Read the article -. It describes in detail the entire process and all the details of deleting and installing the browser.

One of the most common problems when working any browser - when web pages refuse to load. Today we will look more detailed the causes and ways to solve the problem when browser Mozilla. Firefox does not ship the page.

The impossibility of downloading web pages in the Mozilla Firefox browser is a common problem that various factors can affect. Below we will look at the most common.

Cause 1: No Internet Connection

The most banal, but also a common reason that Mozilla Firefox does not ship the page.

First of all, you will need to make sure that you have on your computer active connection to the Internet. You can check this by trying to run any other browser installed on the computer and then turning it to any page.

In addition, you should check whether the entire speed is taken by the other program installed on the computer, for example, any torrent client, which in this moment downloads files to a computer.

Cause 2: Locking Firefox Antivirus

A slightly different reason that can be associated with antivirus installed on your computer that can block access to the Mozilla Firefox network.

To exclude or confirm this chance of a problem, you will need to temporarily suspend your antivirus work, and then check whether pages are loaded in Mozilla Firefox. If, as a result of the execution of these actions, the work of the browser has improved, it means that you will need to turn off network scanning in the antivirus, which, as a rule, provokes the occurrence of a similar problem.

Reason 3: Changed Connection Tinctures

The inability to download web pages in Firefox may occur if the browser has connected to the proxy server, which is currently not responding. To check it out, click in the upper right corner through the browser menu button. In the displayed menu, go to the section "Settings" .

"Additional" And in the sample "Net" In block "Compound" Click on the button "Tune" .

Make sure you have a mark about item "Without proxy" . If necessary, make the necessary changes, and then save the settings.

Cause 4: incorrect work of additions

Some additions, especially those that are aimed at changing your real IP address, can lead to the fact that Mozilla Firefox will not ship pages. In this case, the only solution is to disable or remove supplements 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 \u200b\u200bthe window, go to the tab "Extensions" . The screen displays a list of extensions installed in the browser. Disconnect or delete maximum amount Additions by clicking on the right of each by the corresponding button.

Cause 5: The "Pre-sample DNS" feature is activated.

The default function is activated in Mozilla Firefox. "Pre-sample DNS" which is aimed at speeding up the web page download, but in some cases it can lead to the failures of the web browser.

To disable this feature, go to the address bar by reference about: Config and then in the displayed window click on the button "I take the risk!" .

The screen displays the window hidden settingsin which you will need in any free area from the parameters to right-click and in the displayed context menu go to it "Create" - "logical" .

In the window that opens, you will need to enter the name of the setting. Push the following:

network.dns.disablePrefetch.

Find the created parameter and make sure that it is set to "True" . If you see the value FALSE , Click the Switch Mouse button to change the value. Close the hidden settings window.

Cause 6: Rebupping of accumulated information

During the operation of the Mozilla Firefox browser, accumulates such information as cache, cookies and history history. Over time, if not paying due attention to the browser cleaning, problems with downloading web pages may arise.

Reason 7: Incorrect Browser Work

If no method described above does not help you, you can suspect that your browser works incorrectly, which means the solution in this case is to reinstall Firefox.

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

And after deleting a browser will be completed, you will need to restart the computer, and then start downloading a fresh distribution that will be required to run to install Firefox to a computer.

Greetings you, dear reader! Welcome to wifigid. In this article I will try to tell in detail about why the Mozilla Firefox browser does not open the site. There are different situations - from the complete absence of the Internet before an error of a single site. And in the rarest case, Firefox is to blame. Let's run in the case for each case.

If the problem was solved by another way or questions appeared - write about it in the comments to this article. Let's try to figure out and help other people.

Diagnostics without specials

To begin with, clearly respond to the following questions, because Often the problem is far from the browser itself. After answering questions, find the right section below, and try to work out all the steps to clarify the cause of the breakage. After that, it will be possible to easily eliminate any problem.

  1. Sites do not open completely, or is it just blocked by some element? If completely - go further. If only partially - Firefox has its own screen blocker, which can block some scripts, and they in turn create problems when loading. This will be devoted to the next section.
  2. Do other sites load? For example, this page is easy to load? And Yandex or Google? If a separate site is not loaded - this is one problem, but if all sites are not loaded - the situation is global.
  3. And through other browsers, the site opens? Try to use EDGE or Google Chrome. - How is the situation there? That is, here comply with - the problem is in the browser or all the same on the computer.
  4. We try from another device, for example, from a laptop or phone connected to the same Internet - if the problem is repeated everywhere, then you simply do not have the Internet. What to do? Call the provider, and after trying to configure the router. If everything works everywhere, then the problem is in the final device. Most likely - flew network settings. If nothing was done, then a simple reboot of the router and devices can help.
  5. We try from another Internet - for example, you are sitting out of Wi-Fi, then try mobile Internet. So we can definitely cut off the problem on our Internet or at all. There was a case, the highway was bouncer, and the Internet was not available entirely in the federal district. But most likely, this problem is not yours, because You still went here.

Sites do not open partially

Some people love to use advertising blockers. Are you from that? And in Mozille and takes your own blocker, which people sometimes love to turn on. As a result - the scripts that are necessary for the normal operation of the page are blocked.

If you installed a separate lock plugin (we can't know this) - turn it off. But just in case, check the job full-time. Click here:

When choosing "Standard" - nothing is blocked. I recommend setting the value exactly.

One site does not open

The browser always gives an error why it was not possible to download something. You can just drive it on our site in the search, and most likely you will find her decision.

If all sites open calmly, and some one is not - most likely the problem is in this site. Check on other devices, ask friends. If it does not work, then it simply lies the site. We are waiting, we hope that he will recover soon. Large sites are restored in minutes, medium - within a few hours, but small or forbidden go into non-existence forever.

And very rare Firefox does not have time to update old cookies and cache under the site update. As a result, an error occurs. So for prevention, you can try to clean them:

  1. Menu - Library:

  1. Magazine:

  1. Remove history:


  1. We choose to remove "all" and click on the "Delete Now" button (cache and cookies are marked):

Other browsers open, and Firefox is not

Be sure to check your site in other browsers - if it opens there, and specifically the page does not ship in this Firefox - it means that you need to look for a problem in this browser.

If the problem arose immediately after the update - most likely the bug on their side. The best decision - Reinstall the browser by downloading the new one from the official site.

From problems on a separate site first place takes the use of proxy servers. For example, to go to your favorite forbidden and blocked site you put some proxy or VPN. Over time, they turned off, but the browser is trying to work through them. As a result - nothing works. It was so?

For prophylaxis, turn off them. With VPN is usually more difficult - it can be installed outside the browser (and sometimes antiviruses impose it, so I even recommend turning off the antivirus to check). Those. If you put something, you probably remember where and delete. I'll show you how to check the checkpoint check. We go:

  1. Menu - Settings - leaf down to network settings - Set up:


As an addition, it is rare, but still. Firefox allows you to install the autonomous mode of operation. If set, check that when you need to connect to the Internet, the daw has been removed.

All browsers do not open

If other browsers can not open anything, then the problem is deeper. There may be several factors:

  1. The problem on the computer is from the same VPN enabled to incorrectly issued network settings (if all is configured by automatt, the router and computer restarts).
  2. The problem is on the router - usually routers just do not fly. If everything worked well, 99% that the problem is not here. But many of our readers sometimes reach the absurd - plug new router And hope that everything will work immediately from the box. This usually does not happen.
  3. The problem of the provider is in general, if the Internet disappeared in the house and everything was rebooted, and there is no connection on the router, I usually call the provider immediately. Small failures within a day in a couple of months yes.

What you need to do in the system:

  1. Disable temporarily antivirus - what if it blocks?
  2. Stop correct time - safety certificates sometimes swear at the wrong time.
  3. We reset the cache dns - if the site suddenly updated, then the computer can still search for it in the old location. Reset cache DNS. And rejoice.
  4. The problem of the provider is calling again and learn about the status of the Internet in the area.
  5. Network settings - We are convinced that network settings are exhibited in Automatic mode receiving addresses, and on DNS servers You can specify the same public DNS from Google.
