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".

This clashes with your "Firefox Multi-Account Containers" extension, all of a sudden this doesn't work anymore with facebook.com.

I thought I'd try this, and found that one thing it does is make it impossible to log into a site if you're using facebook to log into that site. When I clicked on the add-on icon I could get a list of sites that were allowed, and there was a section for sites *I* had allowed with nothing in it. And I could find no way to add a site to it. Not by clicking within the app icon. Not by going to manage add-on. And when I googled for help I found a page that said you can add sites but didn't explain how!

Had to remove it.

When I use the facebook container it takes the inbox page out and will not allow me to write post to my business page. The minute I disabled the container I was again able to see my inbox and write post.

I really want to love this addon, but there is no way to add exceptions, and it's VERY aggressive. I appreciate that protection, but I also manage a lot of websites that need to have posts shared and other facebook activity. I still don't want Facebook to track every damn move I make, but without the ability to add sites that will be excluded from the addon's protections, it just interferes with my work too much. I'm going to have to remove it...sadly. Please notify me when you add the ability to add exceptions.

This was working now it's block from facebook or it's been removed by Facebook it doesn't show that it's active. I feel facebook is invading my privacy.

Why won't it let me brouse

It sounded like a great idea...I installed it, it logged me out of Facebook and cleared the FB cookies ast stated, so it got one star. Since installing it blocked all attempts to log in to Facebook. At the FB login page I entered email and password, clicked on the 'Log in' button, but nothing happened, no screen refresh no error message.
When I disabled the add-on, I was once again able to log-in to Facebook.
It did not change the tab colour to blue, I do not have any Multi-Account Container add-ons.
Hence no more stars can be awarded.

Facebook Container is not working on either of my laptops. I've done everything suggested, downloaded the addon, enabled, checked automatically update, but I do not see the blue line under the facebook tab nor do I see facebook in blue to the right of the address bar. I have searched for support for this but have been unable to find any. This app is useless to me as is. Can anyone tell me how to make it work?
