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.

I tried to add it. When I clicked the "Add to Firefox" button this pop up appeared, "Installation aborted because the add-on appears to be corrupt.". It appears the FB IT folks (FB is owned by the NSA, CIA or FBI Spooks) torpedoed your attempt to block them. Nah, I'm just being paranoid again, they wouldn't do that :-(.

The indicator line is SO annoying. I don't need any indications that my tab is contained. I'm just going to put up with Facebook spying on me rather than look at that stupid line anymore making me think it's the active tab.

After adding this app firefox became so slow it was almost unusable, after diabling app fire fox is still slow but better than it was. Crome is much faster.

Can't login with Facebook on certain websites and won't allow me to manually whitelist said websites either.

breaks every websites that use FB login, why can't I manually assign sites to use this container?

This add-on is preventing me from sharing other peoples posts...It's got to go. Honestly I don't think I ever conscientiously asked for this to be "added".
