I can not remove extensions or plugins from 36.0.1 version. I do not have a "remove" button as is described in the page https://support.mozilla.org/en-US/kb/di

Try refreshing Firefox . This link will lead you to a page that will show you how to refresh Firefox. Refreshing Firefox deletes all add ons and settings. Firefox will save these items:

Bookmarks Browsing history Passwords Open windows, tabs and tab groups Cookies Web form auto-fill information Personal dictionary

Have a great day!!

You should be able to remove extensions unless they are not installed in the profile folder, but are installed globally.

Extensions that do not have a "Remove" button are installed by other software and are not under control of the Firefox extension manager. Such globally installed extensions are usually found via a registry scan or are installed in a location that Firefox scans for installed extensions.

Extensions installed this way need to be removed via the settings (options/preferences) of the program that has added this extension or this program has to be uninstalled via "Control Panel > Programs". In Firefox you an only disable such an extension.


Plugins are always installed by other software and are not under control of Firefox. You can only disable (Never Activate) plugins in Firefox in "Firefox/Tools > Add-ons > Plugins".

Ok, as I promised, here is how do this: You can completely remove "plugins" from FIrefox. What you need to do is change things so Firefox can't see them, and they are gone.

Note: This was what I did on my older Windows box. May be different on newer Windows machines... The global way: (Method 1)

 (If the plugins are being loaded via a registry scan...)
 1) open a tab, and select "about:config:"  In the search dialogue box,
    enter string "plug"
 2) Scroll until you find parameter:  "plugin.scan.plid.all" which will be set to "true".  Right-click to bring up option box, and choose "Toggle" to 

set the value to "false". This will stop Firefox from scanning the registry to load plugins. Some of your plugins will disappear. (check your current plugins, by opening a Firefox tab, and entering "about:plugins" All the details of your installed/available/visible plugins will be shown)

The problem with Method 1 is it may not whack all plugins. AND, it WILL whack your Adobe Flash plugin for sure. This sucks, of course, as you will get no video in your Firefox on most sites...

So, Method 2:

 Look at the details in "about:plugins" and find the path names to the .dll files.   The pointer info to run the .dll's is in the registry, but if you 

just rename the file, so it cannot be found, Firefox will just skip the loading/referencing of the plugin.

 Eg:  I had an old VLC plugin installed to "C:\program files\VLC" called

"npvlc.dll". Just navigate to the directory, and rename the .dll file to something like "NoRun_npvlc.dll" If at some point you want to restore the operation of the plugin, just rename the file back to its original name.

And Method 3: You can also, for some plugins, tweak the minimum version number inside the Firefox "about:config" parameter blatherfile, to some level that is really high. That will just prevent the plugin from loading. This is a good way to disable the Microsoft Windows Media Player plugin stuff. In my version of Firefox (version 40.0.2), the value for the minimum usable version was set to "7.0" I just changed the string value to "999.0", and that prevented the plugin for the Media Player from loaded, as well as removing the Microsoft DRM crap. Again, this is in "about:config", in the list of parameters that show up after searching for "plug". You highlight the parameter, press right click, and then select the "Modify" option to change the value from "7.0" to "999.0". This is a kludge, but it stops the plugin from loading, yet does no damage to the Media Player configuration, nor do you need to mess around with fiddling the values of the Registry Keys. Eg:

     "plugin.scan.WindowsMediaPlayer"             was  => "7.0",

now becomes: => "999.0"

I also had Java 7.0 and the Java Deployment Toolkit being found as plugins. The references were in the registry (as freakingly stupid place to put them), but if you just find the two .dll's, which are "npjp2.dll" and "npdeployJava1.dll" and rename them to something else "turnoff_npjp2.dll" and "turnoff_npdeployjava1.dll", then you can re-activate them if you need to at some later date, but they will now not show up in the Firefox list of active/non-active plugins.

I have yet to resolve if removing all my plugins (except the two video players) will allow FIrefox to run without crashing the "plugin-container.exe" module, but I will run some tests... Much of this info is from Martin Brinkman's 2009 stuff on his site: "www.ghacks.net/2009/10/18/how-to-stop-automatic-plugin-installation-in-firefox". (It also explains how to disable/remove plugins). The .js stuff (as he explains in updates) is no longer user-configurable, but the removal options he indicates appear to still work. Martin, you are a scholar and a gentleman. Hope this info helps someone... - Russel F.
