Makes it really clear what container you are in. Huge usability boost. Thanks!

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

When the colours issue is sorted out this will be a good extension.

Useful addon. The cues Firefox provides by default for current container are good but not enough. This addon fills what is missing. It makes it very obvious which container current tab belongs to. I am impressed that someone came up with this idea.

Though there are two issues, at the time of writing, which I hope @jkt will resolve eventually.

1. The colors are too bright
2. https://github.com/jonathanKingston/containers-theme/issues/1

Whilst I've turned it off as the colours for containers all make the app look garish in my eyes, the extension does exactly what it says it will do. Personally I'd prefer more customised styling options for each container rather than just using that colour and splashing it in the tab bar area.

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

This is a great idea. Thank you for creating it.

Unfortunately, it does not work at all for me.

Also, why is it 2MB in size? That's very large for a simple extension.

I think this extension has a lot of promise.

When selecting a tab which is not inside any container the theme is reset to the default theme, not the one I have selected. Also maybe try to adjust the colors when the dark theme is selected. They are kind of bright.
