This article should help - Cannot remove an add-on (extension or theme)

Be aware you you shouldn't leave the plugin.expose_full_path set to true because websites also see that full path via navigator.plugins.

Thanks, but the extension would be one of the "Extensions installed by other software", so it seems like I can't remove (not disable) them from within Firefox? I find it odd, how Firefox cannot control external programs trying to infiltrate the browser. At least I managed to find the extensions folder by myself, it was a subfolder in the program files directory, I was looking for extension-typical files and found it that way.

Oh, so that's why it normally is disabled? I found this to be a useful feature, but ifi t's more secure to leave it disabled, it's the better choice (I think).

Firefox usually finds such globally installed extensions via a registry scan.

• https://developer.mozilla.org/en/Adding_Extensions_using_the_Windows_Registry

That's the solution I've been lookin for! Using Win 7 x64, I looked into the right registry entry and there I've seen the extension bugging me with the path to it.

Yet I still wish Firefox would actually have a built-in way to completely wipe out these kind of extensions for less tech-savvy users (it just feels better to not only have it disabled, but removed), I personally am perfectly fine with this solution.

Thanks cor-el!

If "rid of" is similar to disallow, you can control plug-ins per page by next extension: https://addons.mozilla.org/en-US/firefox/addon/front-shell/

"Allow your installed plug-ins" setting of options page should turn off, and then allow by menu for particular page.
