Facebook Container is not working on either of my laptops. I've done everything suggested, downloaded the addon, enabled, checked automatically update, but I do not see the blue line under the facebook tab nor do I see facebook in blue to the right of the address bar. I have searched for support for this but have been unable to find any. This app is useless to me as is. Can anyone tell me how to make it work?

You cannot add exceptions to the rule, no matter what. Their "work arounds" are made up untested nonsense.
Example: Skout.com, Meetup.com, etc.
You cannot add exceptions. The only workaround is to disable it, link accounts, and then re-enable it, making the entire app nothing more than a useless chore. Use Multi-account Containers instead. They allow you full control. Any container app that doesn't give you 100% simple one-click control is suspicious and bogus.

Einfach nur schlecht. Dieses Addon blockiert neben Facebook-Elementen leider auch noch zig andere Elemente. Ein vernünftiges Arbeiten ist nicht mehr möglich.

Does not work with Waterfox

You folks need to do a browser agent check first to see what your user is running. I didn't login and it let me install it and it made my browser open excessive pages and kept logging me out of facebook. You'd think it'd be easy to do a simple check in the programs setup or something

Simplesmente não funciona no Android!

Aliás, "simplesmente"não! Com muitas firulas animadas louquíssimas.

I gave this a try- HUGE MISTAKE! Now facebook.com won't load at all even after I disabled and uninstalled the add-on. Don't do it unless you want to totally block your access to Facebook.

Doesn't appear to do anything for me (FF68.0.2, Wind10 Pro64). No blue tab for FB pages, icon on taskbar greyed-out...

Pas pisté par facebook mais pisté par firefox.C'est-tu possible d'avoir des modules complémentaires sans être pisté ???

Would not allow to log into Facebook when enabled.

It's likely me; I'm not real computer savvy, but when I went on Facebook nothing showed, no timeline, no friends, etc, and when I posted asking if anyone else could see my timeline, then that post disappeared too. I would love to stop Facebook from tracking me, but the price is too high.

Stopped working about 2 weeks ago.

Doesn't seem to work. Running FF 67.0.1 and when I log into Facebook no images show up at all including profile icons, posted images, etc. All I see is text with blank areas where pictures should be.

It used to be a nice way to isolate your facebook login from the rest of the web. Now it's trying to isolate you from everything facebook does. This breaks all sorts of things, making the addon useless.

I don't like it. I don't know how I acquired it. I would like to be rid of it.

I'm disabling it now. I can't see the benefits, but when I need to login to sites (or re-login after timeout) using my FB account, this plugin blocks the login popup, so I have to disable it temporarily and by doing that it CLOSE ALL my opened FB and Instagram tabs.
