When I remove a firefox addon it leaves settings in about:config

How do I uninstall all the settings it changed in about:config?

Thanks in advance.

Thanks but that's not what I'm looking for.

I want to remove the addons with the about:config entries it leaves behind

One addon I uninstalled left Firefox full of crap in about:config

It also effects the way firefox utilises google search.

Hi: I'm not sure if there is a way to remove everything that a plug-in or add-on changed.

This is a general how-to but Mozilla says you might not remove all changes created when the add-on was installed:


You can try to reset the settings...


but I'm not sure if that's what you want to do.

in about: config just right click> reset

if theres a lot i go straight for the ~/.mozilla/firefox/*/prefs.js
just open it with your editor and delete the lines you don't want.

Thanks everyone.

What I did was rename user.js and pref.js

about:config is now clear of all the old addons and firefox seems to be running smoother.

Nothing much changed on the reload, as far as I can see, apart from noscript settings.
