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.

Great extension. What keeps me from giving 5 stars is that the keyboard shortcuts need to be mappable. It should be one command to open a container tab.

It is a great ideea to bring this feature using this add-on to Firefox, thank you!

Very useful indeed! But I did notice a little problem. When I was in my Personal tab and span a child tab (also personal) to a Medium post as anonymous, one of my cpu cores goes up to 100% load.
That happen every time I spanned the Personal tab with this Medium post.
But, when I opened up the exactly same site on a regular tab (also as anonymous), the cpu was just fine.
So, I logged in at Medium in the Personal context, and the behavior was gone.
That happens on a Firefox Quantum in a Linux Fedora distribution.
