So, there is a container extension put for Firefox that keeps Facebook contained against all else. That is good. Can I use it, now? Yeah. Do I want to? Ehhhhhhhh. Gotta think that one over and over. I wish for additional containers, though, to cover other social networks... including Mastodon.
@shadowstreik And you can set option for first party only. Although when installed most of sites wont work, but you can import some of the rules from github for major websites like youtube, facebook, twitter etc.
