This is add-on is not only amazing, it is essential.
I use it for two reasons:
1. The massive privacy boost.
2. The ability to separate my work and private life. I also use containers for finance and shopping.
Before this add-on I would have to either use a second browser and log-in to different accounts in private mode.
I love this add-on.

the main reason why I prefer Firefox to any other browser
