Like having multiple browsers in one. As well as giving you a way to visually organize your tabs. Super great add-on that shows the real power of Firefox.

Firefox containers makes Firefox my favorite browser. I can have a Microsoft profile and two Google profiles running in the same browser all at the same time without separate windows and I get access to the same extensions that I love because they are all in the same browser.

An essential extension for those who have work and personal profiles and want to keep their logins saved and cookies separate so you can have a "Work Mode" and a "Home Mode".

Toda vez que vou abrir um link, fica me perguntando em qual container eu quero abrir. isso é muito chato. Queria uma opção para evitar essa pergunta. antes estava maravilhoso, eu controlava rapidamente em qual container gostaria de abrir um link. Agora parece que sou idiota: "Você quer mesmo abrir esse link nesse container?".

No more hassling with having multiple profiles opened at same time.

I just started using it and I find it very useful. I don't have to keep separating pages using the private window.
The colors and the ability to sort by container make it easy to navigate through the tabs.

I am so glad this exist. I can finally thwart cross-tracking. I'm specifically a fan of the possibility of assigning domains / sites to specific containers. And it's so easy to use.

Does what it says on the tin, great for administering multi tenant 365 customers.

An absolut must to enhance your privacy and minimize cross-website tracking.

My personal Firefox killer feature. Love it.

Essential for many of my workflows. Works very well.

This is an amazing extension for me since I need to log into my Google corporate account and my personal Google account, and I can have both of them open in the same browser in work and personal containers. Also, having different containers helps me manage web logins and autofills much more easily.

Очень удобно! Все сайты теперь по категориям!

An absolute must if you login to various sites with different profiles.

[2021-Aug] A great and useful extension to have, but it's missing the ability to disassociate a website from *any* (or all) containers. A website's association can be moved from container to container, but cannot be reset back to no container -- something that would be needed in the case of SSOs: to log into the same website with different accounts (under different containers).

It's wonderful!
