The ideia is great, and having a trusted developer (Mozilla) behind is makes everything better. However, it could use some usability improvements when it comes to managing containers/websites, dealing with redirects and opening new links.

Very useful.

One thing I'd like to have (feature request) is to be able to open separate windows, in which new tabs are opened in the chosen container by default.

Very helpfull app! Thanks guys for your work!

One of my favorite apps but please fix it up.

Currently:

It has a problem where it opens double tabs. I have tried every single setting and this still happens at times. it's as if it loads all of the tabs twice, and then sometimes it seems to load them multiple times. have still not figured out how or why it does it. This is currently the worst problem.

Order of the tabs. you can move the tabs around but then when you go to open a tab in a new window you get some random order of your tabs, this seems like a very easy fix.

It would be great to have a way where you could save out the URLs. This would be such a plus as any problems with Firefox, (for example thousands of tabs opening every time you open a certain container) and you might need to refresh or enter safe mode all of your containers are erased. this can be frustratingly sad.

Otherwise this is one of the most powerful functionalities of Firefox

Great add-in, should be built-in! Just one thing missing: it would be great to have a manager showing which site is assigned to which tab group, with the possibility of editing and adding new sites.
Background:
I have an issue with MS Sharepoint links opened from MS Outlook, they open in one tab group (none), are then redirected to another one ('work') for the microsoft login, and finally I end up with the landing page of sharepoint, rather than the document I wanted to open; some info seems to get lost on the way. I think the browser skims over some redirected site which is not in the right container on the way.

Thank you very much, dear developer, for developing such a useful add-on. ❤

Hello world. I love this add-on. I use every day 4 add-ons, included this one. It deserves 5 stars. Thanks to to all the devs who have made it.

The extension is nice, but I wish it was easier to unassign a container from a website.

UwU

please please please, add separate cookies and history for each container, or the ability to disable history per container, or other better customization in the settings other than color and icon.

A must-have for developers. Incredibly useful for multi-user testing.

very convenient to use. Allows me to open several accounts in a browser
