Firefox doesn't work. Why Mozilla browser slows down. Working with Browser Files for Troubleshooting

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, for example, any torrent client that is currently downloading files to the computer, is taking all the speed.

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 that change 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!" .

A window with hidden settings will be displayed on the screen, in which you will need to right-click in any free area from the settings and in the context menu that appears, go to the item "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 the use of the Mozilla Firefox browser, information such as cache, cookies, and browsing history is accumulated. 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.

Many users are familiar with the browser as one of the oldest, safest and most popular navigators on the World Wide Web. The basic functionality of "Mazila" is not cluttered with anything superfluous, it includes only the most necessary and basic (listing, data synchronization, folder creation, tag breakdown, search settings, etc.). Installing additional extensions makes it possible to customize the browser based on your own preferences.

In the process of using the browser, many people have questions about why Mazila slows down, what to do in this case. You can speed up its work in several ways.

Disabling unused plugins

Viewing content of various kinds directly in the browser window is possible with the help of plug-ins. Many of them are rarely used. Disabling them will significantly increase the speed of the browser and resolve the issue of why Mazila is slowing down. For this you need:

Select "Tools" from the top menu.
Open the "Add-ons" manager.
In the explorer located on the side, switch to the "Plugins" tab.
View a list of all installed plugins.
Opposite the plugin to be disabled, in the pop-up menu, select the option "Never enable" (its status will change to "Disabled").

If desired, any plugin can be reactivated. To do this, just change the option "Never enable" in the pop-up menu to "Always enable" or "Enable on demand".

Removing Custom Plugins

The browser does not have built-in tools to get rid of unnecessary plug-ins. However, this can be done through the control panel of the Windows operating system.

This will require:

Through the "Start" button, open the main menu of the computer.
Go to the "Control Panel" section.
Find the "Programs" subsection.
Click on the "Uninstall programs" link.
Find the desired plugin in the list and select it with the mouse.
In the top menu, actions that can be performed with the program will become available.
Select "Delete".
The utility and all its components will be deleted from the computer and, accordingly, from the browser.

Some plugins have their own software that allows you to remove them if they are the reason that Mozilla is terribly slow.

Disabling installed extensions

There are many different extensions for Mozilla Firefox, the installation of which allows you to significantly increase the functionality of the browser (video and music downloads, social networking services, etc.). But do not forget that an increase in functionality due to installed extensions leads to the fact that Mazila slows down. What to do in this case? You need to turn them off. For this you need:

In the "Add-ons" manager of the "Tools" section, open the "Extensions" tab.
Select one by one all the elements to be disabled.
Next to each extension, click on the "Disable" button.
You will need to restart your browser to complete the changes.

Mozilla Speed up your browser by clearing the cache

Sometimes, to increase the browser's performance, it is enough to clear the cache memory.

You will need to do the following:

In the "Tools" section, go to the "Settings" subsection.
Click on the "Privacy" tab.
Click on the "Delete your recent history" link.
In the window that opens, check the box next to the "Cache" item.
Click on the "Delete Now" button.

Clearing all browser history

Users often have a question about why the Mazila browser slows down. You can improve the performance of the navigator in the following way: by deleting the entire browser history. To do this, you need to perform a number of actions:

On the panel located at the top of the browser window, go to the "Journal" section.
Check the box "Delete recent history" (opens a new window).
In the pop-up menu of the "Delete" line, select the "All" item.
Click on the "Delete Now" button.

Changing launch settings by creating a Prefetch folder

Changing the appropriate launch settings will significantly increase the speed of Mozilla Firefox, and the question of why the browser slows down will disappear by itself. To do this, follow these steps:

The next time you start the browser, all information about this will be automatically sent by the system to the "Prefetch" folder. "Mazila" slows down? What to do, we discussed above.

Speed up the minimize and expand browser window settings

If the previous options did not help, and Mazila still works slowly, you can try the following method:

Launch browser.
Enter the following query in the address bar: about:config. Press the "Enter" key.
A warning window will appear in which you should click on the "I promise I'll be careful" button.
A list of all browser settings will open.
Right-click on an empty space.
In the context menu that appears, select the "Create" item, the "Logical" sub-item.
In the new window, in the line "Enter the name of the setting" specify the following parameter: config.trim_on_minimize.
Confirm your actions by pressing the "OK" button.
In the next window, select the value "false" and click on "OK".
Close the browser and confirm the changes by restarting the computer.

After performing such simple steps, the question of why the Mozilla Firefox browser slows down will no longer bother.

Create a new profile

In the case of a long download of Mazila, creating a new profile with the “-p” key will help speed it up. This will require:

Right-click on the browser shortcut on the desktop.
In the pop-up functional menu, go to the "Properties" section.
In the "Shortcut" tab, find the line "Object".
Change the address in it by adding the value "-p" at the end (without quotes).
As a result of the change, the line will look like this: C:\Program Files\Mozilla Firefox.exe -p
Press the "OK" button.

Now you can start creating a new profile:

Launch the browser by clicking on the appropriate shortcut.
The Select User Profile window opens.
Click on the "Create" button.
Follow the prompts of the Create Profile Wizard.

After the process is completed, the old profile can be deleted, as well as the "-p" switch in the settings can be deleted.

Changing Windows Registry Settings

In search of an answer to the question of why Yandex slows down in Mazil and not only, you can come across such a method as changing the registry settings, namely deleting one of its branches. For this you need:

In the "Run" dialog box, enter the "regedit" command to start the registry.
Using Explorer, find the "MozillaPlugins" branch along the following path: [-HKEY_LOCAL_MACHINE\SOFTWARE].
Clear the registry key using the "Delete" functions in the context menu.

After that, you will need to do the following:

Why does Mazila slow down a lot? How to speed it up using third-party utilities?

To speed up the launch of the browser and optimize its memory, SpeedyFox and Firetune programs are enough. Here's what you need:

Download utilities and install them on your computer.
Close Mazila.
Launch the Speedy Fox program.
Click on the "Speed Up My Firefox" button.
The utility will automatically make changes to
Once the process is complete, open the Firetune program.
Select Fast Computer/Quick Connect.
Click on the "Setup" button.
After completing the settings, restart your computer.

The question of why Mazila is slowing down is no longer relevant.

A few more options

Changing some settings on the browser's configuration page will help speed up its work. This will require:

The Mozilla Firefox browser, as a fairly functional navigator, is easy to manage and easy to use, which is what many people liked. Often, with prolonged use, the startup speed of Mazila can slow down dramatically. Each user in this case wants to know why the browser slows down, and what to do to make it work faster.

There are a lot of ways to optimize Firefox (disabling, removing plugins and extensions, changing configuration page settings, using software, making changes to the registry of the operating system, etc.). The choice of the appropriate option depends on the user's skill level, installed add-ons, plug-ins and browser settings.

Hello! Why doesn't it start? By virtue of my profession, I often hear this question in relation to different browsers. In fact, the reason may lie directly in their functioning or the operating system.

Today we will consider why Mazila does not start and what can be done about it. I will share some experience, which in many cases allows me to find and correct the situation for the better.

It turned out to be a decent amount of material. Therefore, for your convenience, I have prepared a summary.

Sometimes the browser starts to work slowly or does not load at all for quite understandable reasons - it happens not only in it, but also in the installed operating system (OS). Let's see what can be done.

Check browser and OS compatibility

The latest version of the Internet browser does not work on all versions of the Windows operating system. In particular, I came across information that the software product is not supported in XP with a service pack below SP2.

But in Windows 7 with the latest updates and XP SP3 Firefox works fine. I checked it myself recently.

What should be done in this case? It's simple - check browser and OS compatibility. I do not give the minimum system requirements now, since by the time of reading this material the situation may change. It is advisable to check the current information on official resources.

Checking your computer for viruses

A common case is that a virus damages or modifies files. At the same time, as the likely consequences, both the browser and all other components of the system are loading slowly.

To exclude or confirm this assumption, you need to do a full scan of your computer. If a virus is detected, it is not enough just to remove it, you must also correct the consequences of its activity. I like to use Kaspersky Anti-Virus to carry out thorough checks of my computer for infection. Naturally, the choice of anti-virus software is the decision of each user.

Finding and fixing bugs in the OS

There are thousands of options here. Nevertheless, I will show one general check and correction of some errors in automatic mode. It helps in some cases when the problems are related to the system processes on the hard drive. It helps me in my work quite often, but I repeat - there are different cases.

Pay attention to the screenshot below. The example was made in XP, but it also works in the seven.

The command shown in the screenshot must be entered into the command line - a program that is standard for Windows. It will search for bad sectors and restore their contents for the specified drive. It is advisable to check all disks.

Update browser and OS

Updates are released for a reason. They may contain modified or added functionality and important fixes. It is logical that they need to be installed in a timely manner.

It is worth doing this at least for security purposes, if the modified functionality is of little interest. In addition, some updates can directly affect the stability of the system.

Working with Browser Files for Troubleshooting

Recommendations of a general type have been considered. Let's say the system is in order, but Mazila Firefox does not want to start normally. Why is this happening? Now I will show 3 more different approaches how you can fix the situation.

We work with the task manager if there was a single launch

It happens that the browser can be opened once after loading the computer. If it is completely closed, then the second time it will not start. The reasons for this may be different.

In some cases, the process simply does not end, although the browser is no longer visually visible. The way out is simple. Open the Task Manager using the keyboard shortcut Ctrl, Alt, Del.

If you see processes with a demonstrated name, they need to be terminated. Their presence means that the browser is not completely closed.

After following these steps, it will most likely open normally. If a similar situation repeats, then it is worth considering other ways to solve the problem.

We clear the browser cache if it starts up and does not work well

A cache is a collection of data that is stored while browsing the Internet. These include, for example, browsing history. If failures occur during Firefox operation, everything takes a long time to load and in some other cases it would be wise to clear the cache. A complete cleaning can be done in a couple of steps:

Removal of web content and user data;
Log cleanup.

As part of the first stage, go to "settings", select the "additional" section and click on the appropriate buttons.

It happens that the above options do not help. Let's see what else we can do.

We perform a reinstallation of the Internet browser and cleaning the profile

We completely remove the current browser through the system tools in the "Add or Remove Programs". We restart the computer.

Open any folder and enter special words in the address bar and press "enter".

I do not remember how in other OSes, but this approach works in XP and 7. So, after performing the above action, a list of folders will open. Among them, we are looking for the name "Mozilla". The folder can be deleted.

Why is Mazila loading slowly and how to speed it up?

I’m talking about this last, so the reasons may lie in incorrect work:

programs that affect the functioning of the browser;
the browser itself.

Some of the ways to solve the problem are given above. If it's not these two points, then what else and what to do then? In this case, the browser takes a long time to load and slowly opens pages for a logical reason - lack of hardware power. Simply put, this is observed when the computer is weak.

Additional Information

The article turned out to be quite voluminous. I tried to remember as many situations as possible from my experience and observations. I would like to draw your attention to the fact that problems can be of a different nature and require individual approaches that may go beyond the options considered.

All kinds of programs and their interaction - all this forms a rather complex system. There are many causes of failures and their solutions.

Mazila is one of the most popular browsers designed for comfortable surfing the Internet.

Browser Features

This browser has a number of advantages over other popular web browsers:

Disabling pop-up window functions;
Analysis and blocking of malicious systems;
Pleasant and convenient interface;
Ability to check spelling.

Unfortunately, a common drawback of this web browser is that the firefox muff is not responding. How to fix this kind of flaws when firefox takes a long time to load and stops functioning? The following are common situations and how to fix them.

Troubleshooting

There are situations when when you click the mouse, Mazila Firefox does not respond. A web browser can hang due to many reasons, therefore, before fixing it, it is important to find out the cause of the hang.

The most common reason why a muff is not responding is lack of RAM.

This program also freezes due to outdated drivers. In this case, in order to fix the problem, it will be enough to update the drivers. Also, it is recommended to disable a large number of plugins and update the extension. If the above steps do not resolve the issue, we recommend that you perform a shutdown and uninstall.

"Script not responding" situation

Next, you need to figure out what to do if the browser of the muff does not respond and after loading a window appears with a similar inscription. This tab appears due to the end of the time for the operation. What to do with such a problem:

Mozilla Crash Reporter

If such a window appears, you should enable the viewer in safe mode. When working adequately in safe mode, it is worth doing the following:

Update or disable all plugins;
Reinstalling or installing another antivirus;
Close unnecessary tabs if their number exceeds ten.

What to do if Mazila freezes and does not respond? What needs to be done if the muff does not respond and leads to the freezing of the entire computer and the absence of a mouse cursor on the request. What fixes can be done:

What to do if Mazila does not respond after long-term use Mazila does not respond? The easiest solution to this problem is to restart the browser. In order to save the data found during this session, you can use the "Restore firefox session" function

To do this, you need to re-enter the Firefox home page. There will be a "Restore previous session" button on it.

Why can the program slow down when restoring a session? The answer to this question is quite simple. When the web page is resumed, several previous pages are loaded at the same time, so the muff does not respond and takes a long time to load. In this case, you need to select the item "Do not load tabs without asking" in the Settings.

Based on the above methods of solving the problem, the most effective solution is to install a newer version of the program. Improved, newer web browsers have fixed most of the problems that their predecessors had. If this does not give the desired results, it is worth performing the manipulations that are outlined in the article or contact a specialist.

Mozilla Firefox is considered one of the most stable and moderately resource-consuming cross-platform browsers, but this does not exclude the possibility of problems in this web browser. Today we will look at what to do if the Mozilla Firefox browser is not responding.

As a rule, the reasons why Firefox does not respond are rather trivial, but users often do not think about them until the browser starts to work incorrectly. It is possible that after restarting the browser, the problem will be solved, but temporarily, in connection with which it will be repeated until the cause of its occurrence is eliminated.

Below we will look at the main causes that may affect the occurrence of the problem, as well as ways to solve them.

Reason 1: Computer load

First of all, when faced with the fact that the browser freezes tightly, it is worth assuming that the resources of the computer are exhausted by running processes, as a result of which the browser will not be able to continue its work normally until other applications that load the system are closed.

First of all, you need to run "Task Manager" keyboard shortcut Ctrl+Shift+Del . Check if the system is busy in the tab "Processes" . We are specifically interested in the CPU and RAM.

If these parameters are almost 100% loaded, then you need to close unnecessary applications that you do not need while working with Firefox. To do this, right-click on the application and select the item from the displayed context menu. "Remove Task" . Do the same with all unnecessary programs.

Reason 2: System failure

In particular, this cause of Firefox freezing can be suspected if your computer has not been restarted for a long time (you prefer to use Sleep and Hibernation modes).

In this case, you need to click on the button "Start" , select the power icon in the lower left corner, and then go to the item. Wait for your computer to boot normally, and then check if Firefox is working.

Reason 3: Outdated version of Firefox

Any browser needs a timely update for several reasons: the browser is adapting to new OS versions, the holes that hackers use to infect the system are being eliminated, and new interesting features are emerging.

This is the reason why you need to check Mozilla Firefox for updates. If updates are found, you will need to install them.

Reason 4: accumulated information

Often, the cause of unstable browser operation can be accumulated information, which is recommended to be cleared in a timely manner. By tradition, complete information includes cache, cookies and history. Clear this information, and then restart your browser. It is possible that this simple step will solve the problem in the browser.

Reason 5: Too many extras

It's hard to imagine using Mozilla Firefox without using at least one browser add-on. Many users install a fairly impressive number of add-ons over time, but at the same time forget to disable or remove unused ones.

To disable unnecessary add-ons in Firefox, click on the menu button in the upper right area of \u200b\u200bthe browser, and then in the list that appears, go to the section "Additions" .

"Extensions" . To the right of each add-on added to the browser, there are buttons "Disable" And "Delete" . At a minimum, you will need to disable unused add-ons, but it will be better if you completely remove them from your computer.

Reason 6: Incorrect work of plugins

In addition to extensions, the Mozilla Firefox browser allows you to install plugins with which the browser can display various content on the Internet, for example, to display Flash content, the Adobe Flash Player plugin is required.

Some plug-ins, for example, the same Flash Player, may affect the incorrect operation of the browser, and therefore, in order to confirm this cause of the error, you will need to disable them.

To do this, click on the menu button in the upper right corner of Firefox, and then go to the section "Additions" .

In the left area of the window, go to the tab "Plugins" . Disable the maximum number of plugins, especially those plugins that are marked by the browser as unsafe. After that, restart Firefox and check the stability of the web browser.

Reason 7: Reinstalling the browser

Changes to your computer may have broken Firefox and may require you to reinstall your browser to resolve issues. It is desirable if you do not just delete the browser through the menu "Control Panel" - "Uninstall Programs" , and perform a complete cleanup of the browser. More information about the complete removal of Firefox from the computer has already been described on our website.

After completing the removal of the browser, restart the computer, and then download the latest version of the Mozilla Firefox distribution from the official website of the developer.

Run the downloaded distribution and install the browser on your computer.

Reason 8: viral activity

Most viruses that enter the system affect, first of all, browsers, undermining their correct operation. That is why, when faced with the fact that Mozilla Firefox stops responding with alarming frequency, it is necessary to scan the system for viruses.

You can scan using your antivirus used on your computer, as well as a special healing utility, for example, Dr.Web CureIt .

If any types of threats are found on your computer as a result of the scan, you will need to eliminate them and restart your computer. It is possible that the changes made by the virus to the browser will remain, so you will need to reinstall Firefox, as described in the seventh reason.

Reason 9: Outdated version of Windows

If you are a user of Windows 8.1 and a younger version of the operating system, you will need to check whether your computer has the latest updates installed, which directly affect the correct operation of many programs installed on your computer.

You can do it in the menu. "Control Panel" - "Windows Update" . Run a check for updates. If updates are found as a result, you will need to install them all.

Reason 10: Windows not working correctly

If none of the methods described above helped you solve problems with the browser, you should consider starting a recovery procedure that will allow you to return the operating system to the moment when there were no problems with the browser.

To do this, open the menu "Control Panel" , set the parameter in the upper right corner "Small Icons" and then navigate to the section "Recovery" .

In the window that opens, select a section "Starting System Restore" .

Choose an appropriate rollback point, dated back to a period when there were no problems with Firefox. Please note that the recovery process will not affect user files and, most likely, your antivirus information. The rest of the computer will be returned to the selected time period.

Wait for the recovery procedure to complete. The duration of this process may depend on the number of changes made since the creation of this restore point, but be prepared to wait up to several hours.
