The Facebook Container Extension does this. The maintainers hard code the list, but it really makes me think that someone can make an extension to let a user manage a list themselves. As an early adopter of Facebook Container, I had to live through when I couldn't log into messenger.com (the only part of facebook I really used). For that specific project, they maintainers wanted to control the list of domains as opposed to allowing users to maintain their own list and "dilute" the effectiveness of the container for "everyone else". Ie, if something was missing, they wanted to fix it upstream and push it down. I would like to see an extension like this for google. I do use google and I have set the various google apps I use to only open in the google container. But the main google.com/search domain does open in any container. I have to be careful if google prompts me to login to not login. https://github.com/mozilla/contain-facebook/issues/45#issuecomment-377623944 https://github.com/mozilla/contain-facebook/issues/45#issuec... https://github.com/mozilla/contain-facebook/blob/1e37bc677acda63e4621d79677131aed9059e1e3/background.js#L5 https://github.com/mozilla/contain-facebook/blob/1e37bc677ac...
