Personal, Banking, Work Place 1, Work Place 2, Junk (for social media) and then a couple others as spares

My key use of this is to manage multiple login sessions to the same site. Having a bunch of spare containers lets me do this in the same browser window. And I don't have to worry about closing them (compared to using private browsing)

Instead of spare containers, you can use Temporary Containers: https://addons.mozilla.org/en-US/firefox/addon/temporary-con...

This is like incognito mode on a container level.
