3 stars because
- each time I go to fb, tab often not being put in a container
- having to set cookie policy each time
- having to login each visit

Using in conjunction with add-on Multi-Account Containers.
DO NOT add a fb container to Multi-Account Containers or it stops Fb Container add-on!

Again 3 years later: Today fb, insta and messenger are not in a container. I disabled and re-enable Fb Container add-on and it immediately contained the 3 tabs.

Ist korrekt in FF 90.0.2 installiert und aktiviert, funktioniert aber nicht. Es erscheint kein blauer Rand um den Tab und die Überprüfung, ob das AddOn funzt, scheint veraltet zu sein, denn nichts von dem, was dort beschrieben ist, tritt auf.

as long as you understand how to use it, then it works fine.

The only problem I've noticed on FB is that if I want to view what was a live video later (after it was saved) the video won't play. If I disable Facebook Container then the video will play.

A must-have !

Loved the concept. Love firefox.
