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!

Straight-forward

With a few ergonomics this could be the biggest development in web browser in 5+ years. It should really be a build in feature of firefox. It gives you a huge amount of control over your privacy and productivity.

Tracking, sessions, and cookies are completely prevalent on the web in 2018. Every site uses cookies, and every other site has a login. Container tabs give you control over that by allowing you to run a different browser session in each container. You can
- prevent tracking by isolating Facebook, Google, and company in their own containers
- Easily sign into many accounts at once
- Use sites while both signed in and out of them
- organize your tabs with colors
All of this is way more convenient than browser profiles because you keep your bookmarks, history, and settings across each container tab.

There are a few downsides to this addon that keeps it being a full 5 stars.
- Your settings don't sync between browsers
- Setting up the containers is annoying
- Limited options for container tab colors and icons
- when other applications open sites in your browsers it doesn't work very well with the containers
- No central place to see all of the sites you have chosen to open in a container

Very usefull for using multiple accounts on a same site concomitantly

This addon is absolutely amazing and I use it every day to keep services separate like google and Twitter to prevent tracking. However, there are two things I wish it would do.

I frequently use more than one computer, often more than 3 a day and this plugin is missing a very important feature; Firefox account sync.

Secondly I find myself really wishing I could manually enter rules for what websites open in what containers, it is a bit tedious to do so right now.

Keep up the great work! :)

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.
