Browser Mozilla Firefox is one of the most popular web browsers, which differs high speed and stable work. However, with a few simple steps, you can optimize Firefox, making the browser run even faster.
Today we'll look at a few simple tips, which will allow you to optimize the Mozilla Firefox browser, slightly increasing its speed.
To be more specific: pop-ups will be blocked, videos will not autoplay, etc. The improvements will be great, especially on sites that have not been optimized for smartphones or tablets. 
As you scroll down the page, you will see the Enable Plugins option. Disable this option and your browser will be faster. The purpose of this article is to collect all the usage tips in one place to optimize your internet browser. So updating and republishing this question will become necessary over time.
Many users use Mozilla Firefox add-ons, which allow you to remove all advertising in the browser.
The problem is that browser add-ons remove ads visually, i.e. the browser downloads it, but the user will not see it.
The Adguard program operates differently: it removes advertising at the stage of loading the page code, which allows you to significantly reduce the page size, and therefore increase the page loading speed.
Configuration can be accessed through the configuration menu and then modules. You're also wasting your time on scrubbing, which can clear caches and end up being counterproductive. The page loads faster. If the cache size and history are too large, it can slow down the browser.
To clear your history, click the configuration menu and select History. Click Clear Browsing History. You will get this window, you can clear it. So, everything is in the Interval to be deleted drop-down menu. Check the cache and two histories. Click the "Remove Now" button.
This is a banal piece of advice, but many users forget to follow it.
Information such as cache cookies and history accumulates in the browser over time, which can not only lead to decreased browser performance, but also the appearance of noticeable “brakes.”
In addition, the benefits of cookies are questionable due to the fact that it is through them that viruses can gain access to users’ confidential information.
This is especially true if the computer configuration is weak. Avoid cumulating extensions, especially protection and others. For example, it doesn't support extensions for phishing sites, although that might seem like a good idea at first. Then a list of extensions appears on the right, you can deactivate the one you are not interested in or even delete.
In fact, target sites that abuse it in particular. For users who tend to open many tabs, there are extensions that allow you to redefine tabs. Thus, the latter are no longer charged and free up resources.
To cleanse this information, click on the Firefox menu button and select section "Magazine" .
An additional menu will appear in the same area of the window, in which you will need to click on the button "Delete history" .
This improves productivity. However, activation is complicated by the fact that many extensions are not compatible with electrolysis. If not, create a value. The page about: memory allows you to visualize memory usage, but it's just not clear, so forget it.
When you have a cleaning line, the impact is minimal. The redder the color, the greater the effect. Of course, the goal is not to fill the browser with extensions, but to have an effect. In the case of memory-free extensions, there is no need to add more than one.
Remove unused extensions
These four web browsers that we will optimize are the most commonly used. Of course there are others. In your browser's "extensions" or "plugins" menu you have all the add-ons installed in your navigation software. These modules are not essential to the web browser, which means that you can remove them without any problems, your browser will still work.
In the upper area of the window, select "Delete everything" . Select the checkboxes for the settings that will be removed, and then click the button "Delete now" .
Disable unused add-ons for now
Removing or deactivating browser extensions will increase the speed of your browser, it will certainly be more stable and less resource intensive. Although some of them may be a guarantee of safety, they are not. Toolbars slow down navigation, can spy on you, and are useless most of the time.
Update your plugins and browser
Keeping the environment in current state - The best way optimizing it and increasing its safety. Most often, updates bring new features and bug fixes, so we highly recommend that you do so.
Delete browser cache and temporary files
These software will allow you to delete files that are burdening your web browser. Depending on your computer usage, you will need to clean it every 6 months on average.Browser add-ons and themes can seriously hinder speed Mozilla works Firefox.
As a rule, users only need one or two working add-ons, but in fact, many more extensions can be installed in the browser.
Click on the Firefox menu button and open the section "Extras" .
Indeed, the files that take up the most space are the cache files. These files speed up browsing and queries posted on the Internet, so deleting them every 6 months is not a problem. However, if this data is too large, it slows down browsing because it requires too much RAM.
Reset your web browser
This is the last option, if your browser is running slow despite all these steps, consider restoring your internet browser to zero. However, the reset process will keep your favorites and other useful data, but make a backup in case.
In the left pane of the window, go to the tab "Extensions" , and then disable the maximum number of add-ons.
Go to tab « Appearance» . If you use third party themes, switch back to the default one, which consumes much less resources.
Edit configuration files
However, these changes don't have too many benefits today and are more likely to harm browser stability than optimize it. Developers different browsers are working in the performance race, not to mention that they do everything possible to make their browser as fast as possible on any type of machine.
Tips for optimizing your web browser
If after all these steps your browser is still slow, try another one. Finally, here are some tips for optimizing your web browser. They often even slow down your browsing experience. A plugin is a third-party library that integrates with the browser. It can be embedded in a web page to work only on that specific page.
Go to tab "Plugins" and disable some plugins. For example, it is recommended to disable Shockwave Flash and Java, because These are the most vulnerable plugins, which can also undermine the performance of Mozilla Firefox.
Extensions or "plug-ins" can be added to the browser's user interface to perform specific operations on pages loaded by the browser. Despite the fact that at first glance they are similar at first glance, plugins differ in that they operate both on the browser itself and on the page.
When prompted, click Restart Now. Select the plugin you want to disable.
- The Add-on Manager tab will open.
- On the Add-on tab, select the Extensions or Appearance panel.
- Select the add-on to disable.
- Click the "Disconnect" button.
Please note that in latest versions OS Windows given the method may not work.
This method will speed up the startup of Mozilla Firefox.
First, close Firefox. Then open your desktop and right-click on the Firefox shortcut. In the displayed context menu go to item "Properties" .
There is a folder in your browser where some downloaded items are stored for later access. Cached content includes graphics, photos, and even entire web pages. When you access a page on a website, your computer first checks the contents of its cache folder to see if there are images on that page, so you don't have to download them again. This will make web pages load faster.
Cache folders can become very large and take up over 100 MB of disk space, collecting graphic files from sites you will never visit again. This will also allow your browser to access updated web pages without interfering with old cached items. To remove cache from internet browsers, follow these steps.
Open the tab "Label" . In field "An object" The address of the program to be launched is located. You need to add the following to this address:
/Prefetch:1
So the updated address will look like this:

Development of web technologies and competition with such a strong rival as Google Chrome, made the Mozilla browser Firefox is better. Today "Fire Fox" is a modern, functional and fast browser. In principle, it has always been modern and functional. As always, Firefox was fast browser, however, until the first overload with additions (extensions and plugins) that make its work more difficult. But if in terms of modernity and functionality Firefox has evolved all the way, then the issue of the speed of the browser as you work with it, alas, is still relevant today. The problem of slow browser operation with a large number of active extensions and plugins on board is officially recognized by its developer - by Mozilla Corporation.
How to speed up Mozilla Firefox? Let's look at several ways to optimize this browser below.
1. Hardware requirements
Firefox is considered an undemanding browser. Firefox itself and its clones, browsers based on the Gecko engine, are often used on low-power computers. Any PC with low performance, in particular, with only 2 GB of RAM, can provide more or less comfortable work with Firefox. "Fire Fox" does not consume as much random access memory, how much is the same Google Chrome. Unlike the latter, Firefox does not clog up the RAM with separate background processes, and all megabytes consumed by the browser can be seen in a single line of manager applications Windows tasks. The mechanism of RAM consumption is simple: the more open tabs and active add-ons, the greater the memory consumption.
4 GB or more of RAM, good modern processor, an SSD drive instead of a regular hard drive will have a positive effect on the performance of any browser. However, the productive operation of Mozilla Firefox largely depends on the software component.
2. Theme and home page
To ensure performance, it is better to avoid decorating the “Fire Fox” with colorful themes. As well as not using extensions built into the browser start pages With visual bookmarks and beautiful effects. Mozilla Firefox will work faster only with its native nondescript theme. The colorful theme you previously installed from the browser store can be disabled or completely removed. To do this, click “Add-ons” in the Firefox menu. The "Add-ons" section is also available on home page browser. And the most quick way to get into it - hot keys Ctrl+Shift+A.
In the add-on management section that opens, switch to the “Appearance” tab and disable the active theme. Both the current theme and inactive themes can be completely removed from the browser.
You can get rid of a third-party express panel with visual bookmarks by disabling its extension. And to return to the initial Mozilla page Firefox if it has been changed third party software, in the browser settings, click menu, then “Settings”.
And in the first tab “Basic” we click the inscription “Restore to default”.
3. Removing extensions
Browser extensions and plugins are a dual thing. Most of them, while expanding the functionality of the web browser, at the same time take away its speed. Because when starting the browser, time is also spent sorting and launching extensions and plugins. You need to work only with extensions that you really need and Firefox plugins, and the unnecessary ones should be deleted or at least disabled. In the browser window, press the Ctrl+Shift+A keys, switch to the “Extensions” section, use the corresponding buttons to delete unused add-ons and disable rarely used ones.
4. Work with Firefox in safe mode without add-ons
You can evaluate the work of “Fire Fox” in absentia without included extensions and a colorful design theme, if you are sorry to part with them for now, you can use safe mode browser. This is a troubleshooting mode that the developers have provided to identify problems. In safe mode, all active extensions and hardware acceleration are disabled, the default theme and toolbar are installed, as immediately after installing Firefox. To start the browser in safe mode, open the menu, click the help button and select the “Restart without add-ons” option.
You can also launch the browser in safe mode by holding down the Shift button while launching. A dialog box will appear asking you to confirm starting in safe mode.
If you hate to part with Firefox extensions and themes, then safe mode can be used on an ongoing basis, and normal mode you can switch only from time to time when the maximum power of the browser is required.
5. Disabling plugins
Not all installed plugins are needed in everyday work, and some of them may not be used at all. Current as of the date of writing this article Mozilla version Firefox installs with two plugins enabled: the H.264 video codec plugin, which is required for playing videos online, and the Primetime content decryption plugin, which is used to check the right to use protected licensed content on individual media portals. After installation in operating system Adobe Flash Player Another plugin will appear - Shockwave Flash. H.264 and Shockwave Flash video codec plugins are needed; they will be used when playing multimedia content and Flash animation. But the Primetime content decryption plugin, if there is no need for access to licensed materials on special media portals, naturally needs to be disabled.
Firefox plugins can be managed in the add-on management section. This is, accordingly, the “Plugins” tab. To disable any unnecessary plugin, if it does not provide the ability to enable on demand, you must set its activity value to “Never enable”.
6. “about:config” settings
Mozilla Firefox has the usual settings section with a visual interface, which can be accessed from the browser menu. But there are other settings - hidden ones. This is specifically designed so that only experienced users or those who strictly follow the instructions can get into them. To get to these hidden settings, enter the following value in an empty Firefox tab and press Enter:
These settings involve a complete transfer of responsibility to the user, and the developers want to emphasize this. In the window that appears, click the inscription “I promise that I will be careful!”
There is no need to worry about such a strict approach: the settings can be returned to their original state at any time. the initial state or, as a last resort, reinstall the browser. The main thing is that the bookmarks are exported and created backup copy or synchronization is configured using account Firefox.
Mozilla Firefox has a lot of hidden settings, so for quick access to them there is a search field at the top of the window.
Changing any of these settings requires a browser restart.
6.1. Disable tab opening and closing animations
To benefit browser performance, you can get rid of the tab opening and closing animations added in recent versions. In the settings search field, enter the following name for the setting and press Enter:
On the settings line highlighted in blue, double-click with the mouse so that the default value “true” is changed to “false”.
6.2. Disabling Prefetching
One of Firefox's features, Prefetching, allows it to preload into memory the contents of links that the user is most likely going to open next. In theory, Prefetching speeds up the opening of web pages, but on slow computers, loading pages in background can significantly reduce the performance of the system as a whole. Moreover, this function consumes too much traffic.
To disable link preloading once and for all, find the setting named network.prefetch-nex t and double-click to change its value from “true” to “false”.
6.3. Speed up loading web pages
To get to the site, its server needs to send a request. Taking into account the possibility of working with a weak Internet channel or an overloaded server, Firefox is configured by default to send a small number of requests. By increasing the number of these requests in the browser settings, we will seriously speed up the process of loading web pages. This tactic, alas, cannot be called 100% effective, since the servers of some sites (usually actively visited) may not be able to cope with the load. In this case, instead of the page loading, you may see the message “Service Temporarily Unavailable”. If this is not technical work on the site, then you need to wait a minute or two, and you can try to get to the site again.
To speed up the loading of web pages, enter the following setting name in the settings search field and press Enter:
We do the same with the settings network.http.pipelining.ssl And network.http.proxy.pipelining, if you are using a proxy).
Settings network.http.pipelining.maxrequests determines the number of simultaneous requests that will arrive to the site server. The recommended value is 32.
Another way to speed up page loading in Firefox is to enable new system HTTP caching, which is disabled by default.
Finding the setting browser.cache.use_new_backend, open and change the value from 0 to 1. Click “OK”.
7. Fasterfox extension to speed up loading web pages
Alternative the previous method speed up Mozilla Firefox - Fasterfox extension. It, in fact, is a visual interface for the “about:config” settings that were described in the previous paragraph. Fasterfox can be installed for free from the Mozilla Firefox store.
In add-on management (Ctrl+Shift+A) we get access to the settings of this extension.
In the settings window, you can select one of the proposed sets of browser performance settings. For example, a lightweight option with optimization of only the visual part of the browser, or an extreme option with the maximum number of requests to the site server.
This is a more suitable way to speed up Firefox for less experienced users, since if something goes wrong, Fasterfox settings can be used to set different sets of optimization settings or return to default values. As a last resort, the extension can simply be disabled or removed.
8. Return to original settings
Any failed experiments with settings and Mozilla add-ons Firefox - no matter whether it is related to performance or other problems - can be removed without reinstalling the browser. It can be returned to its original settings. In the Firefox menu, click the help button, then in the pop-up sidebar, select “Troubleshooting Information.”
In the tab that opens, click “Clean Firefox” and confirm the decision in the dialog box.
This isn't exactly a return to your browser's original settings, as some data will be retained, which is for the best. In the process of such cleaning, a new profile Firefox, into which bookmarks and authorization data (logins and passwords) on sites will be transferred. Everything else - settings, extensions, themes - will disappear.
9. Clear cache
One of the rules for speeding up any browser is to periodically clear the cache. To clear it, in the Mozilla Firefox window, press the Ctrl+Shift+Delete keys. A window for deleting browser history will open, where you can select the period for which cache data has been accumulated and the ability to set other parameters. To see these options, you need to expand the “Details” option.
We will see a list of data that will be deleted. You can delete the data selected by default, but in order not to re-enter logins and passwords for authorization on sites later, it is better to uncheck the preset checkbox from “Form and search log”. That’s it – all you have to do is click the “Delete Now” button, and the Firefox cache will be cleared.
