Making an extension solely to block Facebook from being a creep on other websites. Common Mozilla W.

Using this for years now. Love it!

It blocks too many sites/pages or their operation improperly _ HUN : Túl sok oldalt vagy annak működését nem megfelelően leblokkolja

Ok

В сочетании с блокировщиком рекламы и поисковиком типа DuckDuckGo даёт прекрасный результат. Тестировал несколько лет. Спасибо разработчикам за прекрасный продукт.

THIS EXTENSION LOGS YOU OUT OF ALL FACEBOOK ACCOUNT WEBSITES!

Just a heads up, this extension will immediately sign you out of every single website you've used "Sign in with Facebook" with, including Facebook itself. If you don't already have a password manager, to auto plug-in creds, you'll have to re-sign into every website manually once you remove this extension.

v2.3.9 breaks a number of sites including gog because it excessively messes with the is-hidden css class, even when unrelated to facebook.
