Fantastic. Honestly, should be a built-in Firefox feature. Works fine out of the box, but I use it in conjunction with the Temporary Containers extension, which makes it even more powerful.

awesome add-on

AMAZING!

Very useful for maintaining multiple profiles, forget the old ways of having multiple browsers for multiple accounts.

Firefox Multi-Account Containers have definitely made my internet browsing, both business and personal, a very pleasant experience. Even my app cleaners agree because I don't clean hundreds of junk, privacy, and registry files.

I gave Firefox Multi-Account Containers a 5 star rating because it's UI is easy to use, very intuitive of the Developer's to include color-coded cards that I create specific to my needs. You can even use your password manager without a hitch while inside of the color coded tabs.

You are also able to right-click on a new or current tab to open a context menu; and, given the option to re-open your tab, select your specific folder, and the new tab is underlined with your color--let's you visually know what they are.

I've been enjoying the containers, not just for privacy purposes, but also for easily splitting user profiles when doing testing/support.

My one piece of feedback would be that a more automated approach to choosing and opening in containers (e.g. with shortcuts) would be a great improvement.

One of the most useful add-ons ever.

A melhor opção de todos on navegadores/extensões para gerenciar várias contas. Bonito, rápido, simples e customizável.

Juste parfait... Permet de segmenter les cookies, d'ouvrir plusiers onglet vers le même site avec des identifiants différents (plusieurs boite mail par exemple).
Indispensable !!!

Essential.
