Still not sure whether, and why, these containers are needed when Firefox's internal ‘tracking protection’ is enabled.

  For anyone else wondering, this is now “content blocking” and by default is in private browsing mode only but can be set to always on. Sounds like a good idea. https://support.mozilla.org/en-US/kb/tracking-protection https://support.mozilla.org/en-US/kb/tracking-protection

    I've thought for a minute when looking at that option, and couldn't think of why I wouldn't want it, so turned it on. IDK if it misses anything but seems to be working pretty good, judging by messages in the console. It's rather aggressive, even: blocks Yandex's maps embedded on other sites (though iirc doesn't block Google's maps).

      It does trip a lot of “turn off your ad blocker” nag screens.

  Firefox tracking blocking is a fairly weak "make the web a bit safer while breaking nothing". This extensions actually does break stuff like google logins on non google websites.
