How To Uninstall Firefox Add-ons With No Remove Option
You can uninstall most Firefox add-ons from the addons manager page in the web browser. All you need to do is type in about:addons in the address bar and tap on the enter key to open the page.
A click on remove next to an add-on uninstalls it from the browser. You may need to restart the browser afterwards depending on the add-on to complete the process, but the add-on has been removed completely from the web browser when Firefox restarts.
Some add-ons on the other hand do not show a remove option at all in the addons manager. Most of the add-ons that you cannot uninstall from within the browser are called global extensions.
They are installed from third party sources, for instance when you install or update security software or another application on your system. The Babylon Toolbar is an example extension as it is often attached to software installations.
Uninstall Firefox Add-ons without Remove button
The majority of extensions are installed in the extensions directory of the Firefox profile folder. I'd suggest you start there to see if the extension that you want to remove from Firefox is listed there.
One of the easier ways to find out where it is located is to type about:support in the browser's address bar and hit enter. The page that opens lists an option to open the profile folder under "application basics" near the top.
You may run into two issues when you look at the list of installed browser add-ons. First, that extensions sometimes install with cryptic names so that it may be difficult to identify them, and second, that you may not find the extension that you want to uninstall listed here.
The easiest way to identify add-ons here is to load them into archiving software like 7-zip. Double-click on the install.rdf afterwards and look for name there.
Some extensions are already unpacked in a folder. Just open the folder of the extension in that case and double-click on the install.rdf file in there to identify its name.
It is however likely that you do not see the extension that you cannot remove in the directory.
Global extensions can be installed into any directory. The most likely folder is the extensions folder in the Firefox installation folder. This is usually C:\Program Files (x86)\Mozilla Firefox\extensions for 64-bit Windows operating systems, and C:\Program Files\Mozilla Firefox\extensions for 32-bit systems. Keep in mind though that you can install Firefox into any directory. Portable Firefox users need to open the extensions folder under the portable path.
Repeat the steps outlined above to identify all extensions listed here.
The third and final option is the Windows Registry. You may find extension information under the following two Registry keys:
Use the shortcut Windows-r to bring up the run box. Enter regedit in there and hit enter. Navigate to the keys in the Windows Registry and check if extensions are listed there.
Information that you will find there include the extension path.
Backup the Registry key first by selecting File > Export. Open Windows Explorer and navigate to the directory of the extension. Backup that directory as well, before you delete both the directory and the Registry key that links to it. Repeat the step for all extensions that you want to delete.
Please note that you need to close Firefox before you start deleting extensions on the system this way.
If you follow the method, you should be able to delete any extension that you cannot uninstall from within the browser interface.
To sum all that has been said up:
- Check the extensions listing in the Firefox profile folder first.
- Afterwards, check the extensions listing in the Firefox installation directory or program folder.
- If the extension was not listed in either location, check for extension references in the Windows Registry.
Great information, Martin.
Cryptic names are a headache.
I have WinRAR and that should work.
Yes Winrar, Winzip and most other tools can be used as well.
Thanks for the tips. Easy way to find out the ID of an extension is to go to about:support where they are all listed.
Marika, great tip. Thanks
The question is why are there add-on with no remove options .
Good tip. However, there are some things a novice might have difficulty with while following the instructions.
It would be good to mention that .XPI files use ZIP compression and are ZIP files (but do not use a .zip extension) and that the .RDF files are text files.
The .RDF files might be opened in a text editor when 7-Zip is used (I have not verified this), but that may not be the case when executing from the Windows using the file’s association.
how is this news, and why it is showing up in Google News when searching for Firefox?
Go to help menu & select troubleshooting information
refer extensions its just simple
You said to type in about:addons in the address bar on the Add-ons Manager page when it opens up. THERE IS NO ADDRESS BAR WHEN YOU OPEN UP THAT PAGE.
I said to type about:addons to open the add-ons manager.
It is a shame that firefox allows this kind of unsafe behaviour. All extensions should be uninstallable from an admin interface without requiring acessing directories or, even worst, using the registry. Apparently there is no good and safe internet browser for windows anymore. Thank you for your help.
FYI: For Windows 7 x64, the global Firefox extension registry location is at:
I had a hard time finding this and that was where my bad extension was hiding.
Ken, thank you! I thought maybe my install was corrupt because I couldn’t find the extensions in any of the places people were telling me they should be.
Then I found your post!
Yessssssssssssssss i have deleted it from registry. Its so easy but take care while deleting registry files. Thanks its really works.
Ken above is correct, I needed to look in Wow6432Node to find the extensions I wanted to remove.
It’s also far easier to open about:support (or go to Help->Troubleshooting Information) and look there to find the ID for the extension you want to remove, rather than unpacking all your.xpi files.
this post is awesome dude you just saved me a lot of trouble… Thanks.
There is another place where FF stores internal extensions which it actually doesn’t need, “C:\Program Files\Mozilla Firefox\browser\features”. The problem is, you don’t know what they do. I used the good old TCPView to check what connections FF opens after start when no web page is open yet. It was a lot. It connects to servers like:
Once you block these connections via the lmhosts file, nothing happens. It only can’t check for updates anymore. Well…
Just wanted to thank you. This article is still relevant even today in 2023. Back in 2015 I installed the standalone “IDM_7.1_Full_By_Live-Technology”, a hacked version of the then “not free” IDM software and included a plugin/addon. The plugin was useless but the standalone worked great After using it for several years, web site security started changing making my hacked IDM unable to connect due to site security changes. In 2019, even after uninstalling the IDM software from my XP64 pro with FF52.9ESR, IDM was still showing up in Firefox addons as incompatible, disabled and no remove option, so I just lived with it until now. I just spent the last few hours trying to get rid of this annoying glitch. I tried every technique I found and the only one that finally worked was the Global Extensions registry modification of HKEY_CURRENT_USER\Software\Mozilla\Firefox\Extensions\ to remove all entries related to IDM. Started firefox and presto, the IDM addon was gone. Again, Thank You Very Much.
