really cool and helpful

Very nice but it is annoying to ask twice to remember the website assigned container by default. Why?

Great for privacy, great for multi-account access. Does what it says on the box.

To improve:
- Remove the "Open this site in your assigned container?" step, it's completely unnecessary. I've already said I want it, so do it.
- Allow (specific) extensions to work across containers, because I have to re-enter my LastPass password every time I open a new container, which is annoying.
- Ability to sync container config with Firefox account, for multi-device access.
- Ability to edit containers more efficiently, much like one would bookmarks. I'd like to be able to copy a folder of bookmarks and paste them into a container all at once.

Five stars if you save the containers and config for the site on firefox account and sync...

This is a really great extension that makes life much easier managing multiple clients.
What would be helpful in the future are adding key-bindings and synchronisation.
But again, great tool that I now use everyday. Thank you!

Definitely an improvement to be able to separate sessions. REALLY needs keybindings to open tabs in each container. It's really painful to have to click in order to open a new tab in the container I want to open a new tab in (and locking domains to a particular container doesn't really help all that much for domains where I intentionally want to switch context).

It needs sync to be able to be the same containers across all my Firefox installations on all platforms.

Really Great. It would be nice to add possibility to copy move tabs between containers.

It doesn't sync. I would like to share the same container types between my computers. I have a Mac and a PC.

El concepto de los contenedores, cuando lo entiendes, tiene mucha utilidad.
