At every firefox new updates, firefox '''insists '''on restoring extensions that I have disabled/uninstalled because they are completely '''useless '''to me and '''I don't want to use'''. Enforced Useless (and maybe security risk) Extensions: '''Amazon''', '''Bing''', '''eBay''', '''Google''', '''Twitter''', So, Why does Firefox '''insist so much''' on reinstalling '''unnecessary''', '''useless '''disabled/uninstalled extensions and "features"'''?'''
