Je l'utilise au quotidien et il fonctionne parfaitement.
Très utile pour avoir plusieurs sessions sur un même site :)

Dope add-on!

Works perfectly for every site I have set up, except for Twitter. I have set up a container for Twitter, but any time I open the site, it doesn't open in the Twitter container, even though I have checked the option for it to do so. I will use this add-on from now on, but I would like for this tiny flaw to be addressed and fixed.

excellent tool. use often to logon to multiple gmail accounts, along with social media sites that I have two user IDs.

Perfect to keep work and personal separate.

Не хватает только возможности сортировки списка контейнеров.

I missed this feature so much from Chrome, finally I realize it was here all along. It's stylish and works great. Love it.

Excelente plugin! Agora no meu browser, o google, facebook, jornais, sites de compra, trabalho, fica cada um isolado no seu cercadinho.

At first I though this looked like it could be useful, but after installing it I didn't really start using it and just kind of forgot about it until recently.

After actually using it for a while I can confidently say it's absolute gold.

Must have sur Firefox, j'avais quitté Firefox pour Chrome il y a de nombreuses années maintenant sans trop m'intéresser aux évolution de Firefox, à tort je le réalise maintenant.

Je reviens sur Firefox maintenant et cette extension ne fait que conforter ma décision !!!

Je voulais un système de ce genre depuis longtemps, je peux enfin efficacement combattre le ciblage sur le web. Un plus serait d'offrir une option qui isolerait tous les onglets non associé à un conteneur, mais ce serait peut-être trop gourmand en perf.

I slept on this one for too long; container tabs are awesome! Totally streamlines my workflow without compromising on (a reasonable degree of) privacy. As someone migrating from the noscript-and-autodelete-cookies-on-everything way of life, this is sooo much better. Thanks, Mozilla!

Would be nice to add more colors to edit the tabs, but still really beautiful!

I would like to have more control if Firefox is installed on different computers in different languages. I have different names for one logical container: f. e. "Arbeit" and "work"
