It works well for always opening a specific site in a container, not sure why this is an addon instead of being part of the built-in containers though.

Excellent.
Though at the early time it might be confusing for new users.

You can lose your data. Do not trast this add-on! Very raw product.

Great concept, but the interface is clunky and the Sync feature doesn't seem to do anything. With a more powerful configuration tool (e.g. let me supply patterns such that any matching URL will be forced into a particular container, with no confirmation dialog) it would be perfect.

解决了我的大问题,希望可以提供快速添加的功能,我需求比较多,一次能添加一百个就好了

Great add-on; please consider adding the ability to sort the containers based on various criteria like name and date created.

I wish the container settings allowed us to configure cookies and history policy specifically for certain containers so it would stop certain websites for looking up history? It would be nice. Like private window but in normal window container. I would rate it to 5 if it had that feature

This containers app is so useful and awesome, definitely gives firefox an edge (no pun intended) over other browsers!

Good idea in principle, but will only work with my email account for a week or two, then instead of opening container it throws me back to the email log-in screen. If I disable or remove this add-on, all is well.

Multi-Account Containers is a very good extension, but it could be excellent. For exemple, creating a private navigation tab/container could be great !
