How to remove extensions in Mozilla. How to remove a plugin from the Mozilla Firefox browser
Probably every Internet user knows or has heard what a browser extension is. If you are not aware, then this is an application that is installed into your Internet browser from a special built-in store and adds to it additional functions and opportunities. For example, using various kinds of extensions you can be able to download videos from various services like YouTube, instantly receive notifications from social networks, even when they are closed, and much more.
In the event that you have already installed this or that add-on in your browser, and now you want to stop using it and you need to find out how to remove the plug-in from, then this depends on how it was installed. There can be two scenarios here, in the first of which the application was installed official way from the store, and with the second, an external installer was used in the form of a *.exe or *.msi file.
Add-on from the store
If the application was installed from the store, then to remove it you will not need to use anything other than the built-in capabilities of the browser itself. To remove a plugin in Mozilla, you need to:
- Launch browser double click by shortcut on the desktop, or single if the program icon is located on the taskbar or in the Start menu.
- Click on the button with an icon of three parallel bars, also known as the “hamburger menu”. This button is located on the right top corner FireFox windows, and when you hover over it, a hint “Open menu” appears.
- In the list that appears, select the “Add-ons” item, on the button of which there is an icon with a puzzle.
- Open the “Extensions” tab on the left side of the page that opens.
- Opposite the unnecessary plugin, click on the “Disable” button if it is not needed only for a while, or “Delete” if you are going to get rid of it forever, losing all its settings.
So that you do not have any difficulties, and you can easily find everything necessary buttons inside the tangled FireFox menu, I prepared this illustration, on which I noted all the elements and names mentioned in the instructions above: 
In most cases it is enough simple shutdown extensions, without complete removal. Typically they don't take much disk space, and if you just temporarily do not need the functionality of a particular plugin, then you can simply disable it.
Control Panel
If the browser extension you are using was installed via executable file*.exe, that is, it was not downloaded from the FireFox directory; in this case, plugins are removed through the panel interface Windows management. The procedure is standard, and to complete it you only need:
- Close the browser window if it is open.
- Open the Start menu.
- Go to the “Control Panel” section.
- Open the “Programs and Features” category.
- Find an unnecessary addition in the list.”
- Right-click on it.
- Select “Delete” and follow further instructions to uninstall the application. Most often everything happens in automatic mode, and you only need to wait for a message that the deletion was successful.
All the steps described above are performed as follows: 
Important! If you have Windows 8 installed on your computer, then in order to find the classic Control Panel, and not the Settings application, press the key combination “Windows” (the one with the logo) and “C”, after which a menu with charms will open (Charm-bar). From this panel, tap the Settings button, and then select Control Panel. A shorter way to open the Control Panel is to press the “Windows” + “X” keys and select the appropriate menu item from the list that appears.
After you have removed the application from the Windows Control Panel, it is a good idea to open the FireFox browser and check if the plugin is still in the list of installed ones. Go to the menu "Add-ons" - "Extensions" and check the list installed applications. I described how to do this a little higher in the article.
Reset FireFox
In this situation, if after the above steps an extension that is unnecessary or interferes with the normal operation of the browser is still shown in the list of installed ones, and is not removed correctly due to some error, you can try resetting FireFox. This action also answers the question of how to remove plugins in Mozile, as it completely returns the browser to its default state. To perform such a rollback to standard settings, you will need:
- Launch FireFox.
- In the address bar (where the site address is entered), enter the words “about: support” and press the “Enter” key to go to system page browser.
- On this page, click on the “Clean FireFox” button and confirm this procedure in a pop-up message.
After the user gives permission to carry out the operation, the browser closes and restarts. Literally within a minute, the browser’s operation is restored, and it appears in its original form, as if it had just been installed on the computer. It will check again to see if FireFox is the default browser on the system, and the first message will say that all settings have been reset to default. All user data will be placed in a specially created folder on the desktop. In general, this method is more like a desperate step when other solutions no longer help get rid of an unnecessary extension.
I think today we figured out how to remove a plugin from FireFox. I hope that the methods described will be enough to solve the problem, and you will never have to resort to the third method.
I am glad to welcome you friends to my blog. In today's article, we will talk about how to remove a plugin from the browser. Mozilla Firefox. A plugin is a special addition to the browser that can solve specific user tasks.
With the help of plugins, you can significantly expand the functionality of the browser and make it a universal tool for solving many problems. But at the same time, it is necessary to monitor normal operation these plugins, their relevance and need for use. If you no longer need one of the plugins, then you can safely get rid of it, since in addition to the load on the browser itself, this is another unnecessary potential vulnerability.
Important! Through the Mozilla browser Firefox, you cannot delete the plugin, there is no such option. It is possible to disable it.
Later in the article, I will tell you how to remove the plugin if you need to. But first, let's look at the process of disabling the plugin.
So, launch the Mozilla Firefox browser, press the key combination:
Ctrl + Shift + A
and go to the Plugins tab on the left side.
Select the plugin that you no longer need to use and on the right side opposite its name, select Never enable from the drop-down list. Make sure that the word Disabled appears next to its name.
That's it, the plugin is deactivated and no longer works.
How to remove a plugin from Firefox
If the option of disabling the plugin does not suit you and you want to remove it, then follow the instructions described below.
Method number 1. Uninstalling plugins using the Control Panel.
Click the Start button and go to Control Panel, then select Uninstall programs (I am considering the uninstall option in Windows 7; in other operating systems, your task is to find and go to Programs and uninstall them).
Almost every installed plugin has its own uninstaller. Therefore, we find an unnecessary plugin in the list of programs and remove it. IN in this case we are looking into the plugin Adobe Flash Player.
Method No. 2. Removing plugins using a dll file.
Important! Before deleting a plugin, I advise you to first disable it, as described at the beginning of the article.
Launch your browser and address bar type the command:
after which you will see a complete list of installed plugins in your browser. Find the plugin you don't need and pay attention to the line called Path under the plugin name.
Let's take an example Shockwave plugin Flash (let’s imagine that our video plays poorly, or it doesn’t work at all, a fairly common situation among users).
We see that in the Path line we have the full address to the final library called NPSWF32_18_0_0_209.dll, which we need to delete.
Unlike the latter, it has more functionality, more extensions and, which is quite important, can check spelling. It also has some protection, although, of course, this should be done by an antivirus with a firewall.
It should be noted that the browser is cross-platform and can work not only on Windows. Many necessary ones have long been ported to others operating systems, which the browser can work with. Thus, the already mentioned spell check can be performed not only on Windows, but also on Linux.
Having learned about the possibility of extensions for the browser, inexperienced users can sometimes install so many plugins that it actually starts to slow down or freeze. This raises the question of how to remove a plugin from Firefox. You don’t have to delete it, you can simply disable it - an inactive plugin will not create problems, but later the question will still come up. And what to disable, what to delete - all this is done from one window. Below we will look at the removal options, but first you should understand where and how you can find plugins.
Installing the plugin
"Ognelis", as some users call it, has its own huge database of plugins, where you can choose an extension to suit every taste, color and opportunity. For example, to check spelling you need a dictionary plugin. There are several versions of these dictionaries in the database, from basic to advanced. The fact that the browser has a Russian interface is also achieved by the plugin (originally “Ognelis” was English-language).
For example, this is what the process of Russification of a portable version or an erroneously downloaded English version looks like.
Against the required version Click on the “Russification” button (highlighted with a square) and on the “Install” offer - we agree. Then we restart the browser. The rest of the extensions from the base are installed in the same way.
Sometimes “Install in Firefox” buttons appear on third-party sites. Most often this is some kind of extension for working with this site. It is up to the user to decide whether to install it or not. Installing this option is no different from installing from the database.
Download music, video
At a separate level there are plugins that allow you to download music or video from popular media hosting sites and social networks. Some allow you to download only from VKontakte, some from other resources. For example, the VKontakte plugin for Firefox allows you to download photos, music or videos from groups and pages of the VK network. At the same time, there are plugins that allow you to send a link to a site to your wall, VK, My World and several other networks.
If the question is only about downloading, you can look towards the plugin from popular service- "SaveFrom.net". In principle, the service allows you to work without a plugin - the search bar is right on the site, but using the SaveFrom.net plugin greatly simplifies downloading various media content. For pages of audio and video recordings on VKontakte, it offers a “Download” button directly on the recording, but it understands not only “VK” - the current list of supported sites can be viewed at home page service, and here we mention that among its functions there is the ability to download videos from YouTube.
A green “Download” button appears on the video page. Clicking on the button offers several formats from which you can choose the desired one. Note that the plugin for Firefox browser, as for others, is not in the above-mentioned database - it is installed from the network or from the service website.
Setting up plugins
Basic actions with plugins, including removal, are performed from a special window. The window moves from version to version, but regardless of the installed “firefox” it is located in the “Tools” - “Add-ons” menu. There are several menu sections on the left, but we are interested in the most top line on the right side of the window. A magnifying glass, a search field to the left of it, and even further to the left a gear-shaped icon - a drop-down list. There is a check hidden in this list Firefox plugins for new versions.
There are few settings, but these are common to everyone. Let's translate into Russian. Top down. “Check for updates” gives you the opportunity to quickly find updates and, if there are any, install them. The second item can show what was last updated and when. Most often useless. The next item is separated by a line; if you have reset your browser, you may have saved updates somewhere on your disk; you can install them using this button. The two items below control the update. The second one from the bottom is usually turned on, and Firefox, having learned about the updates, will immediately install them, and the last one you turn on is automatic - the browser updates all plugins without asking you. If for some reason you do not want automatic update- for this there is a second point from the bottom. By clicking on it, we will reset the checkbox, further updating will be at the user’s command.
Removal
In the same add-ons window, the question of how to remove a plugin from Firefox is also resolved. Let's go to desired menu, select the extension or plugin, then click the “Delete” button, which will appear in the highlighted line. In case of some difficulties, you can act in several stages. First stop, then delete. Sometimes the program will need to be restarted between these steps.
Febe
The main aspects have been discussed, but one of the features for which users love the Firefox is the ability to quickly unfold it into its usual form. Let's imagine a situation - reinstalling the OS. After new installation The installation of programs begins, then each program must be configured in a form familiar to the user. Developers from Mozilla have created an application that will allow you to return installed browser familiar look. Moreover, even if you downloaded the assembly, you don’t have to think about how to remove the plugin from Firefox, this extension will do everything. All you need is to install it before reshuffling, save your settings for applications, bookmarks, browsing history and even
After installing Firefox on new system you need to install this application again, your usual applications and restore their settings. The app is called FEBE. At first you need to understand the settings a little, but after several experiments, working with the plugin will not be difficult even for a first-grader.
Let's look at a situation where, after installing a crooked plugin or a software glitch, the browser stops starting. In this case, it doesn’t matter how to remove the plugin from Firefox. It is more important to restore the functionality of the entire program. For such cases there are third party services, for example Mozbackup. According to the developers, this program Works not only with Firefox, the entire line of Mozilla programs is supported.
The program can “pull” everything you need from a non-working browser - bookmarks, cache, history and, among other things, “customized” extensions. The program works simply, at first you will be asked what you want to do - “Save” or “Restore”. Then in a new window there will be a selection of components that the program can process.
The selection is impressive - from basic settings to the download list. Select what you need and, depending on what you selected earlier, restore or save. A version with a Russian interface is also available online.
Conclusion
Some users are wondering about Firefox. After all, the program hid this feature from the main settings. The update works automatically by default, but rebuilding this function, manually checking, adding or removing plugins - all this now happens from one window.
How to disable or remove a browser plugin
As you know, the Webtun website is dedicated to reviewing the Internet, and also reviews browsers and we try to share it with our readers useful tips connected to one degree or another with popular browsers. I am sure that readers of our site know what a browser is, for those who have forgotten, let me remind you that it is a program for viewing websites (, etc.), except
In addition, on our website you can get acquainted with various interesting plugins, that is, modules that are connected to the browser to expand its capabilities (playing music, videos, viewing documents).
But it is worth keeping in mind and not forgetting that the browser and/or its plugins, so-called extensions, may be unsafe. The simplest
a way to protect yourself from virus attacks from the Internet is to regularly update to the latest stable version browser, as well as monitor updates of your used plugins. Otherwise, your browser will be vulnerable and there is a chance of being exposed to virus attack via browser. You won’t even notice anything: just go to an infected site, and all your passwords will leak to the hacker. According to statistics, 90% of users can get a virus at any time due to vulnerabilities in the browser or its add-ons. By browsing websites through an unsecured browser, you risk downloading malicious file, which is not detected by antiviruses. The download usually occurs secretly, without your knowledge or consent. In most cases, such viruses transfer all your passwords, credit card numbers to the “owner”, view and steal files on your PC. But that's not all: your PC may be part of the virus, and this danger is also not detected by antiviruses. In this case, the computer will perform various commands, participate in sites, can become a participant in mass spam mailings and are generally completely at the mercy of attackers.
If the browser itself is vulnerable and a security update has not been released for it, we recommend temporarily using a different browser. If a vulnerability is found in a plugin, we recommend temporarily disabling the plugin or switching to alternative plugins that provide similar functionality.
Below are the guides for popular browsers showing how to disable or completely remove the vulnerable plugin:
