While I love the idea of this extension, it causes too much breakage on certain sites. For example, this extension breaks Sharepoint online or any other site inside of Microsoft 365/Azure that has an embedded Facebook widget. It causes the page to get stuck in an infinite login loop if you try to allow the widget or causes the page to display incorrectly otherwise. Not recommended if you use Firefox for work with Microsoft 365.

There is probably a good reason for this, but I do not fancy needing to login anew, every time I open Facebook. That gets old extremely fast, so I'll ensure my privacy in other ways, thank you.

On the same day I first heard about a very specific product and searched for it using DuckDuckGo through Firefox with the Facebook Container installed and running, I saw an ad on Facebook for that exact product model. I had not been searching for other related products prior to this search, so it is not possible that Facebook inferred my interest in this product and this was simply a creepy coincidence. The only plausible possibilities are 1) Facebook Container failed to isolate my search from Facebook's tracking, or 2) Facebook truly does listen to conversations using laptop/smartphone microphones and uses this for targeted ads.

Every time I enable this extension my machine slows down drastically, even though I have no Facebook tabs open.

After installing I am no longer able to log in to facebook, even after deactivating the Plugin. After 30 seconds I receive a log-in error. is there a fix? Do I have to deinstall and reinstall firefox?

I lost all my cookies

All cookies are lost after installing.

Has been working fine. As of today, I can't open Facebook with this addon enabled. It's as if the site address can't be resolved.

yep, same as a few people, i can't log into facebook any more. not seen any support available for this issue either.

after starting i can't log in to Facebook

Not available for android

Doesn't appear to do anything. The popup from the menu bar is blank. Tabs while on Facebook don't turn blue.

Response to Developer:
The address bar does not change. There is a fence icon on my tool bar. When you click it, there is a popup and it is blank.

I CAN NOT DOWNLOAD THIS!! PLEASE GET IT TOGETHER FIREFOX!!

Couldn't get firefox to update - ubuntu. Hence, no FB Container. Will try later.

There is no obvious way to add an allowed site.
