I am unhappy because updating Firefox for Windows automatically adds/recommends this extension, but updating MacOS browser does not. I had to manually search and add this extension to my MacOS browser. Come on Mozilla, treat both OS's equally, not fair.

I love it for multiple accounts in the same browser

This is a really useful, lightweight and perfectly working add-on for Firefox. Especially compare to Firefox profiles. Helps to organize sessions for different accounts at same services. Another convenient function is to assign addresses to particular containers. That one is so perfect. OMG. Thx, guys. Could be convenient to add functionality to see what sites what containers assigned.

Should be built in by default. I love this.
