cool add-on. would be great if you could contain any social network / website. Also... does this work for messenger.com as well?

Awesome. This has been needed for a long time. Kudos to the devs!

Not available for Android, but that's where I use Facebook.

Exelent add-ons

This is an excellent idea - and if you only have one Facebook profile you want to have open at once then it seems flawless.
However for myself I usually have a work and home one open - with Firefox containers I have had one in Personal and one in Work. It would be great if this extension could open more than one account at a time.

unable to install, greyed out on Firefox page.

We should make this app for every damned corporation.

awesome add on to stop fb spying on us.

+1 for privacy

Missing support for ESR version of Firefox

Needs to be contained.

Can't seem to get it to work. Nothing happens on FF 60.0b7. Does this extension only work on regular release?

Awesome!
Now please make a similar addon for Google. They're just as bad as Facebook when it comes to privacy. Thank you in advance.
