I added the Facebook and multi-account container extensions. I opened Facebook, logged in, and it's not opening in the container (no blue underlined Facebook on the right side of the address bar). I tried adding pages to my other containers, but when I click the + beside the container, nothing happens. The extension window closes and nothing else happens. I tried disabling and enabling the extensions. I removed them and added them back. Logged out and back into Facebook several times. It's still not working. I also read over the existing article titled "Facebook container isn't working", and that didn't help me at all. I'm not sure what steps to take now to fix whatever the issue is.
