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!

useful for keeping work and play separate!

One of the most useful add-ons I have ever tried. This really helps clean up account-hell if you want to keep your identities separated.

A useful extension.

It couldn't be easier to organize my sites into containers. Every feature I felt like I needed was already there to use and easy to find.

Very easy to use. The ability to keep categories of websites separate has greatly enhanced management of my privacy.

Just really useful! Hope it also had a "default site" for each container.

Funziona benissimo. In futuro aggiungerei anche la possibilità (opzionale) di tenere separata la cronologia tra i vari containers.

It will be great if the assigned sites and containers could be synced with the firefox account so users don't have to assign website on different devices separately.

Truly amazing extension.

Très utile pour séparer différentes activités (notamment bancaires et commerciales) du reste de la navigation. D'autant plus que le paramétrage permet d'ouvrir systématiquement certains sites dans un container particulier
