I really like this addon and use it for two use cases: 1. multi-account usage and 2. privacy protection
I don't need to explain the first point - that should be clear.
I have tested the 2nd point thoroughly and can confirm the following: It works.
- to lazy to write examples - so test it on your machine ;-)

4 stars for thank you and also for supporting DARK THEMES, but it's not very simple to manage. I use it for years but I never understood it, like for example why the default named containers like work, shopping etc. I use it together with "Temporary Containers", also difficult to manage. (Note that this firefox page is ridiculously and revengefully "protected" from dark themes!)

I have used this for add-on for quite a number of years, have never experienced any problems, and appreciate the role that it plays (with the Facebook-container package as well). Lastly, as an add-on it's been vetted by Firefox, which should be another layer of correctness and security for the code.

Common your synchronization are shit, i lost all my open default sites switching between Floorp and Firefox, in firefox lost all my custom containers and data (in floorp are ok, but cannot restore in firefox)

Absolutely invaluable
