Just works without any problems

It allows you to separate the information Microsoft, Google and Facebook, know about you and put them all on a need-to-know basis.

It's a killer functionality that makes Firefox worth using, just for this.

I use different google accounts for YouTube and YouTube Music and keeping different container tabs for each site has saved me from the pain of having to toggle back and forth for each one

Enserió una de las principales razones por las que uso firefox, te permite tener todo separado pero a la vez en el mismo navegador y usando la misma cuenta

Chrome was obliterating my system memory and this was the best alternative I found to Chrome's tab groups.
