Really useful! As other said, with this extension, it's easier than ever to manage multiple accounts and be able to use firefox in multiple settings. I highly recommend using containers in combination with simple-tab-groups.

I had been using other browsers at work like edge chromium and chrome and using firefox for my personal / internet research. This is exactly what i was looking for, something that would allow me to consolidate to just Firefox and separate work from personal and everything else.

I love this add-ons so much. Thanks firefox!

It separes my accounts, my personal account, my institutional account and more

Seems to work as advertised and as such is a pain free way of keeping a degree of separation of ones various online lives.

This add-on is must have for those who seek to keep their environments such as work and personal separate.

A life saver. I can now keep my personal email and my work email open at the same time, not to mention both of my kids' school accounts.
