Most useful addon for me, especially in comparison to other browsers. I am not logged in all the time for example in Google, and can use several accounts of the same online service. And it remembers, which URL should open in which container, if I want.

It's a great idea, but suffers from horrendous UX

Habe Themen basierte Container angelegt. Die Tabs innerhalb eines Container vermindert sich so erheblich und muss nicht mehr lange suchen. Insgesamt eine Erleichterung bei der Arbeit.

hard to change "Open this site with container..."

This is just TERRIBLE! I don't recommend it to anyone. This extension significantly slows down the browser, works terribly slowly, and takes a long time to load pages. Moreover, it constantly requests permissions from the same site. Save your nerves and look for another solution!!!

The idea is great, but there is some problems with it.
Firefox has two different mechanisms for data isolation:
1. Different Firefox profiles
2. Containers that can be used within the same profile.
+ Additionaly we can use different OS user profiles.

It would be better to be able to open different tabs or windows within different Firefox profiles or OS profiles.

I could not do my work without this possibility to use the same sites in different contexts (different users, instances, workplace)

Continue to see tabs in containers even after deletion of the extention.

Very useful extension! THx!

A little fidgety to get started but works for my purposes, great effort.

If your using multiple SSO accounts from the same vendor... dont lock the 'login page' in to a specific container! Works as intended but can get confusing. If using services from the same provider just dont lock them, open the respective container and it will open the links in new windows of the same container...
