While installing an update for another program, I didn't pay attention, and suddenly the Babylon search toolbar is installed in Firefox. I could remove the Babylon program from Windows, but the Firefox toolbar is very persistent. I can disable the toolbar, but there is no remove button. I've tried to remove Firefox, then remove all Mozilla folders in the AppData folder, I removed the profile, but both the Babylon and Avast addons are there.
How do I remove these addons completely? I don't care about removing profiles etc.
