Firefox 74
The Facebook container is great, but I wish there was an option for the built-in Multi-Account containers to work this way. I've been doing what the Facebook Container extension does, but with built-in containers, and the experience is very clunky.The two biggest issues are that I can't give the container a list of domains beforehand and say "everything under google.com should open here". I have to go to each Google subdomain and set it to "always open in this container" with three or four clicks. The other major issue is that there's no way to have links outside those domains open outside the container, so whenever I click a link on Gmail that goes to Github, Github opens in the Google container and I always have to copy/paste the address to a new tab.Fixing those two annoyances would make the built-in containers feature amazing. Maybe I should file a feature request.EDIT: I have filed a feature request: https://bugzilla.mozilla.org/show_bug.cgi?id=1621276
