Overall great for doing exactly what it says: It cuts down on the tracking that Facebook and its affiliate websites carry out, including links on other websites. My only problem that I've had personally is that there is some odd glitch that occurs due to the Container that causes the tab to flicker, opening and closing itself in a repetitive loop. I have yet to figure out a means to stop this happening, and as such have pretty much just stopped using all of Facebook's sites entirely except for occasionally poking at the Instagram app on my phone.

I have been using this since it first came out. From what I can tell, it has worked great with no problems. Now, in late August 2020, after allowing the new Facebook interface to take over in my Facebook, I found that the new Facebook look/interface does not play nicely with Facebook Container. My Firefox eventually freezes as does everything on my computer. As soon as I disabled Facebook Container, everything worked again. Hopefully this issue will get fixed soon.

How do i hide the container button, It keeps getting in the way of some images.
I like it but it's just an annoying floating button at this point.

User friendly! Nice!
