Love it, helps me a lot.

Would be great to choose a custom theme for each container.

The addon currently has a small bug but the creator is working on fixing it. I do love the feature as the multi-containers colors are too small to really notice.

Excellent extension, thanks! Agree that colors are really too flashy

That's a very convenient idea. This way I see clearly what container I got open and won't confuse or forget what container I'm using.

I use containers for admin account sites in special containers. The themes have reduced my error rate considerably!

This helps me use containers more productively - it's now really obvious which container I'm in.
