Good stuff. Agreed with another review - don't really need a warning. Now that the basics are down (excellent add-on!), I'd like for some enhancements. Basically, you know why I'm using the extension, so perhaps offer to automatically containerize popular websites (offer container packages). I think I'd like to be able to put every site in its own container, too, unless this would obliterate performance. Thank you! :)

Great extension, but I would like the ability to re-order the containers, and perhaps group them using dividers.

Sync is broken, default container names reappear on install, deleted too, waiting for someone to fix it, or I will, if I get off my lazy ass one fine day in the future

Great work by mozilla.

Must-Have addon for privacy minded folks (in combination with https://cup.aihedy.com/en-US/firefox/addon/temporary-containers/)

This is useful but I hate when opened all the tabs of a container I close Firefox without hiding them and I lose the container content. Since I spend time to organize my containers I would expect to have it persistent somehow.

На линуксе при использовании контейнера некорректно работает автоопределение орфогафичкских ошибок, из-за чего весь текст красный. А так все прекрасно работает на винде.

I love the concept of keeping several contexts. Now I can keep the must-login-but-will-track-your-online-activity sites in their own containers, and surf the web without Google/Facebook/... following me on every click. Also makes me feel a bit safer, knowing my work and bank related website cookies cannot be abused by random sites I pass by. A missing feature however (and the only reason I'm not giving 5 stars) is that it isn't linked with bookmarks, it would be so much better if bookmarks could have a setting "open in container", that would probably also fix Tab Stash, were now all tabs are restored in default container.
