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!

This is an instant ESSENTIAL tool for modern web browsing to reduce cross-site tracking. I sure feel a heck of a lot better having the most obvious tracking sites (Facebook, Google, Microsoft, Amazon) isolated from each other.

Great feature. Previously missing sync, but now that's been added.

This extension should be built into Firefox to complement the browsing experience (because there are not tab groups)

Game changer!
