great add-on, does the job well and is well integrated in the browser. Still some work to do to improve integration even further but there are regular updates. Good job folks

I've been using it for a few months when suddenly my custom containers disappeared and now I need to create them again.

FIXED: I had to log in and get it synchronized. My containers are back.

This extension is a must-have. It is very useful to separate your work/hobbies/customers so that you can use the Google, Microsoft or Atlassian suites each with only what concerns each ecosystem. All this separate from social media. I couldn't do without it anymore.

Great. Have really just got to using it a whole lot more since started new job - very good for organizing your projects. Simple, Intuitive. Stable so far, no issues. Recommended.

Not bad. The only question I would have is - can you have wildcards for "always open *.example.com" in container XYZ?

Very useful

This is add-on is not only amazing, it is essential.
I use it for two reasons:
1. The massive privacy boost.
2. The ability to separate my work and private life. I also use containers for finance and shopping.
Before this add-on I would have to either use a second browser and log-in to different accounts in private mode.
I love this add-on.
