A great addon that makes Firefox an even better browser. Being able to have separate environments for separate "personalities" integrated into the browser like this is fantastic. Just being able to log in with two entirely separate accounts to the same site at the same time with the same browser is huge for me.

very helpful

one of the best feature of Firefox, maybe best implementation of tab groups

this add-on is what keeps me on firefox

BEST EXTENSION EVER !!!!!!

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
