I believe what people says: "cant imagine daily browsing without this ext." or "this shouldnt be only an extension, but part of the integrity of firefox". I prefer to say this is firefox supremacy.

very useful tool for multi account login

This extension should really be integrate to the main code instead of being only a extention.

It's an absolute necessity. Enriches the built-in containers feature and makes it truly useful. Couldn't live without this.

Excellent plugin, cannot imagine everyday browsing without it.

I do miss two customizations
1) An option to assign individual bookmarks to containers
2) Changing order of containers in right click panel
