This is a must have extension, and it makes Firefox very awesome.

This is a killer feature! No need for separate profiles/browsers and the headache of managing them.

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.

Still figuring this one out. Sometimes things are going very wrong and sometimes they are working just how I wanted :-) I will keep persistent and learning, as I like the idea of having some control over Google, Facebook, Amazon, Microsoft.

能修改网页标题就完美了

Container implies that it holds something. I was hoping that each container would hold one type of website that i often have many open - such as youtube. I want a youtube container that I could throw videos in to watch later. Watched several how to videos for this adon but nothing was said about that. Tried to see if it would work like that. Don't think so.
Better if Firefox called this thing "accounts" or something like that as all I can figure out is that it separates accounts.
Somebody tell me I'm wrong and it works that way the name implies.

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.
