This extension must have by default!
Great!

Most valuable add-on for my workflow to have it all in one browser and even window. Perfect for dealing with different environments like DEV, STAGING and PROD and multiple Accounts.

Great Addon for privacy

This feature has been very useful to me. Especially with regards to separating work and personal accounts and functions.

This is a very useful addon. Ability to login with multiple accounts at the same time is very useful

At work, I have to deal with multiple accounts for the same platforms, like Outlook 365 and Atlassian. This add-on helps me a lot by separating the sites by category and allowing me to open only one browser window to access everything.

Highly recommended for anyone with a lot of tabs. Create however many groups you need, hide groups you're not actively using, and show groups when needed. Save memory by hiding tabs you don't need until later :)

Excellent add-on for separating accounts.

great idea

Super convenient way to make sure cookies don't track you all over. Gives more control over how websites can track you.

Works great.

Excellent et facile d'utilisation !
Continuez ainsi !

Ottima applicazione per separare le tipologie di account, puoi accedere con 2 account contemporaneamente allo stesso sito ad esempio a youtube per vedere le differenze o per usarli con preferenze diverse oppure puoi memorizzare le credenziali di accesso solo in una categoria e queste vengono usate solo se apri un tab appartenente a quella categoria.

Awesome!

my new must-have addon on Firefox!
