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!

Very usefull for using multiple accounts on a same site concomitantly

Que ferais je sans lui, c'est un bonheur pour tout admin de site qui a besoin de tester la vue par différents utilisateurs!

Es muy fácil de usar, cómodo y muy útil, práctico es algo que nunca creí necesitar pero que me ha ayudado mucho, adoro poder tener diferentes sesiones en una misma ventana.

bagus sangat membantu saya..tingkatkan lagi

one of the best addons. i can open multiple rstudio server tabs in the same window now! :D

Finally! This was a long awaited feature but this add-on is an elegant and powerful way to handle multi-accounts and profiles in Firefox. For those (as myself) who thought that profiles management was THE feature that lagged behind Chrome in Firefox, this now does more that catch up on it!
