I have been using this since it first came out. From what I can tell, it has worked great with no problems. Now, in late August 2020, after allowing the new Facebook interface to take over in my Facebook, I found that the new Facebook look/interface does not play nicely with Facebook Container. My Firefox eventually freezes as does everything on my computer. As soon as I disabled Facebook Container, everything worked again. Hopefully this issue will get fixed soon.

Great concept, but it breaks Facebook Workplace (won't sign in) so I cannot use it. Needs the option to whitelist domains, perhaps.

is ok

So far, so good....I haven't had any issues with this extension - innovation like this is so important to allow us to take control of our own data. Thanks Mozilla - keep up the great work you're doing.

Занёс случайно в этот контейнер ссылку на сайт https://yandex.ru/ . Теперь этот сайт ВСЕГДА открывается только в этом контейнере. Ссылка в меню контейнера не видна. Переназначение другого контейнера не происходит. Отключение контейнера не помогает. Помогло только удаление и повторная установка. Влияние контейнера Firefox Multi-Account Containers на описанную ситуацию не проверялось. Однако этот контейнер на всякий случай тоже был переустановлен.

It works, I guess, but everything... is... so-o-o-o-o-o.... slo-o-o-o-o-o-o-ow.

Hur installeras facebook container? Ingen hjälp anges???

Nur einen Stern, weil man damit keine Spiele spielen kann.

i want to delete facebook container. how do i do it

I really appreciate the effort from Mozilla to protect our personal data, but this blocks Workplace, which is very inconvenient! I really hope they can address this issue soon.

It works fine on my Windows destop, but is not available for my mobile and my tablet as they are on Android - but I go on FB far more on those devices than on my work PC...

When activated, facebook is out but at the same time I'm unable to log to gmail or other websites (without using facebook-login dear trolls).
Gmail says that my browser is not secured and ask to install a recent one. Other websites ask for recaptcha and repactcha is unable to work properly when this add-on is activated.. This require to be improved.
