Facebook containers are a killer frature. As soon as I bought a new laptop and became able to afford using Firefox (it was too slow on the old one so I had to use Chrome-based browsers as they worked much faster) I don't have to use multiple browsers nor multiple browser users in separate windows to isolate specific websites. This is awesome. By the way there is a more sophisticated version of the extension which would let you configure rules so specific websites would open in specific containers automatically.
