Not sure what I should be noticing, so tough to tell if it is working.

Since first installing, this extension appears to have worked well. But as of today, 7 January 2021, something has gone wrong: on logging in to Facebook, I get their generic error page. If I disable the extension, Facebook works as normal.

I love this extension, EXCEPT...
It has a mandatory button on the address bar taking up precious url space and I already have other addons doing that, and so I encourage the developer to add an option to remove this button and be able to depend solely on the pinnable button to indicate the active container as I prefer (by way of switchable icons).. Thank you for your consideration...

Nice concept, but i`m missing "exclude containers from sync" based on wildcard or prefix.

The the first time use all fine. Now is impossible surf into de FB platform w/ this ext enable. Very slow reponse, page not load completly, need hit f5 over 10 time for get page full loaded. If I disable this etx. FB run perfect. But w/out isolating :(

Please, fix this issue.

nice, but it blocks access to mapillary.com too (that's a facebook company)

Great when it works... sometimes it magically disappears and I have to disable/re-enable to make it work work again.

With the last version ? Alert without any reason on every email field even if there is no link with Facebook. It's at least the case on my own website where I only have a LINK to the facebook's page that's all.

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.

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.

Good extension but the white bar at the top is very distracting and makes me feel like my facebook tab is my current tab at all times, I would appreciate if this white bar could be more subtle

As of today, 28 Mar 2021, Facebook Container 2.1.2 is BROKEN for 78.9.0 ESR 64 bit. It worked in 78.8 ESR 32 bit, but locked me out after the upgrade. When I turn the extension off, Facebook reappears. Remove, restart, and reinstall doesn't help.
[edit] This version WORKS PROPERLY on 78.8.0 ESR 64 bit. I checked it on other versions running on my network, sync'd to the updated 78.9.0 ESR 64 bit.

I like this extension but every time it pulls into a container it wipes history of the tab which is kinda annoying. I can't seem to see a setting for that so that might be a future feature

Instagram tab gets unpinned every time I restart firefox. Facebook and messenger sites are working normal.
