If you value your privacy and want to mess with how we are tracked online, this add on is great.
If you have several users (who trust each other, I suppose) sharing the same browser instance, then this can save you a lot of logging in and out (yes, I know, not a secure practice, hence trust is implicit, but secure or not, it happens).
Both of the above I do routinely, and I have really appreciated this add on for that.
For me, though, where it really shines, is in the following too situation:
- I play a web game where it allows me to be logged in to several instance,
- opening a new container is often a fast hack that allows you to bypass the article count in some websites.

So, in sum, if there is any situation where you would like one browser instance to behave as several instances with separate contexts, this is for you.

And huge thank you for the developers, for coding this, and for doing so in a Free/Open Source app! May your kindness and dedication come back to you and bring you joy!

Amazing. So handy to ensure gmail doesn't automatically spread it's tracking session across all of my browser tabs!

Container history should be separated too even though it seems impossible. Maybe just autofill container separation.

Such a useful extension for multi-account management. Now I can have Office 365 apps for both my companies open without messing with each other.

Really an amazing add-on for anyone juggling multiple identities, including multiple AWS accounts.

A must-have in work environments. Nice to have at home too.

That's what i needed, along with simple tab groups i can navigate through the web without sign in each time.

Overall fantastic in separating cookies. One thing it needs is ability to hide the history of the containers from the main browser history. Either it should have option to keep no history just cookies for signing in etc. or show separate history for each container.

Guys it is a bit frustrating to use at this time. Missing options:
-DONT ask for confirmation every time you open a container - just open them in default or enable option of choosing default container for new tabs.
-I would really prefer shared logins across all tabs. I just need to group them but it is a bit counter productive to login to 10 gmail accounts and then have to login to X different places again and again due to new group.

Enkelt att hålla isär skolarbete och personliga sökningar, allt i samma fönster och webbläsare, men med olika flikar. Funktionen att alltid öppna en viss sida i en specifik container är till stor hjälp, och det är enkelt att växla container för aktuell sida om så behövs.
