Containers are amazing and have removed the need for me to use profiles as I did in Chrome now that I've switched to Firefox.

Two improvements are needed:
* [p0] BUG: when restoring (unhiding) tabs in a container into a new window, I get duplicates of all tabs. If I restore the container tabs into an existing window this bug does not happen.
* [p1] There should be a way to send all open (or subset) of tabs to a container
* [p1] I would prefer the default action for a new tab to be the last tabs container (without needing the ctrl+). Alternatively I would love to have a window be marked as a container and have all new tabs in that window associated with the current container by default.
* [p2] I want container sync to FF Android :D !!!
* [p2] Another nice to have would be to have different extension settings or even enable/disable extension settings per container.
