Today I accidentally discovered Firefox's "containers". This lets you run tabs in separate private "spaces". This video explains and shows you the set up.
Thanks for the explanation! Next time instead of typing 'facevook' or whatever, type F . You don't need to type out all urls when the browser autocompletes it for you
For a minute I got excited that I would be able to have completely different profiles like Chrome with all the bookmarks syncing etc on the different user profiles. This isn't like that, is it?
No it's not profiles in that sense. I don't think Firefox lets you do that at all. Containers keep your stuff together, but present a different identity to the internet for logins and tracking. It's like opening a different browser, but in the same browser!
