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.

Firefox a beau me dire que Facebook est dans le container, je vois bien que le "Partage/Like" sur mon compte est toujours possible depuis les autres onglets.
Inutile, donc désinstallé.

Love it! Firefox's containers are the killer feature that led me to make Firefox the browser I use almost exclusively. And the Facebook container is the one that started it all for me.

Doesn't work very well as I still get targeted ads after looking something up in a different tab.

still able to "like FB" on other website

Excellent

Great addon that seems to do what it says. However, it's not available on Firefox mobile.

With Facebook Container turned on, when I type a message to someone over Facebook, it becomes jumbled and a mess. Pressing enter closes all chats, amongst other annoyances.

With Facebook Container turned off, all of these issues go away
