Супер! Давно искал нечто подобное!

This extension alone makes Firefox a better browser than any out there.

Being able to separate your workplace(s) related tabs from everything else:

* reduces blast radius in case of a security issue
* allows you to run everything within the same browser

I use this to replace all the Slack/MS Teams/Mattermost/Discord/etc stuff, and it's a blessing!

I love it!

Ottima estensione utile ad esempio quando si usa un account Google personale ed uno aziendale. Segnalo un piccolo difetto che riguarda l'associazione automatica di una pagina ad un container: non è facile capire come tale associazione si rimuove.

The easier way to have multiple microsoft accounts.
An indispensable extension for developers to test different roles on your apps simultaneously.
This extension must be part of Firefox.

five star review

Great. Now I have the control of all my accounts.

I'm stunned that this feature isn't standard in all browsers. If you have multiple Gmail and social media accounts, it's a life saver!

This is an instant ESSENTIAL tool for modern web browsing to reduce cross-site tracking. I sure feel a heck of a lot better having the most obvious tracking sites (Facebook, Google, Microsoft, Amazon) isolated from each other.

Great feature. Previously missing sync, but now that's been added.

This extension should be built into Firefox to complement the browsing experience (because there are not tab groups)

Game changer!
