Супер! Давно искал нечто подобное!

This extension used to be amazing, but out of nowhere it stopped working correctly. Now my containers are no longer sandboxed and when I login on one, I have to log out on the others. This is exactly why I use it, to not need to sign out when switching from one login to another, and it is no longer of any use to me.

This extension alone makes Firefox a better browser than any out there.

Being able to separate your workplace(s) related tabs from everything else:

* reduces blast radius in case of a security issue
* allows you to run everything within the same browser

I use this to replace all the Slack/MS Teams/Mattermost/Discord/etc stuff, and it's a blessing!

ask user want which container to open is not necerrasy.

"要用您指定的容器開啟此網站嗎" 是多餘的動作

I love it!

Ottima estensione utile ad esempio quando si usa un account Google personale ed uno aziendale. Segnalo un piccolo difetto che riguarda l'associazione automatica di una pagina ad un container: non è facile capire come tale associazione si rimuove.

The easier way to have multiple microsoft accounts.
An indispensable extension for developers to test different roles on your apps simultaneously.
This extension must be part of Firefox.

five star review

This COULD be really really really good, but they need to put some thought into it, and it looks like they once did but removed some of that due dilliigence in the Great Firefox Rustification, because you used to be able to reset a site's "Always open in" association by right-clicking anywhere on the site, but now, I have zero f*** clue how. And if you set a site to always open in a container, and now you have to login to a different account that logs in with Google? Well Good luck bud. Use a different browser, and just hope you don't need 2FA from a client who's in a meeting I guess.

Most usefull capablity of any browser I know. Please continue working on this.
It would be usefull to better sync between devices all the windows and tasks I have opend. Something like in Safari but with the container capabilities. That would be great.

Great. Now I have the control of all my accounts.

Not the best... It takes too long to open every time the proper container before open a web page. I wish I could link up every single url to the specific container and make bookmarks of it. So this extension is just half-productive.

I'm stunned that this feature isn't standard in all browsers. If you have multiple Gmail and social media accounts, it's a life saver!
