The extension works very well, but it would be great if the rules didn't affect manually created groups. The Enable/Disable function doesn't work correctly because every so often, I don't know if it refreshes or what, but it reactivates the rule and if you've made any modifications to the group, it undoes them. If you could fix this, it would be a 10/10 extension!

Installing this extension completely and immediately deleted all my already created groups! This is too bad!

Hello! thanks for your work on this wonderful addon

I wanted to request two feature additions:

Other tab group: This would function as a catchall for other tabs that are not part of any other groups. this would keep things tidy in the physical spaces between tab groups

Rule ordering: It’s unclear to me how a tab is evaluated if both “github.com” and “github.com/issues” are rules that assign to different tab groups. In this situation, having rule ordering would be a great help.

Thanks so much!

Very useful add-on to make tab groups really practical for everyday use.
Currently I still see some glitches, especially when adding/editing regexes, where the add-on claims the rule was added when in fact it wasn't (probably due to a parse error in the expression).
Feature ideas: Add a full screen page for configuration with better overview when you have a lot of rules.
Offer config sync across multiple firefox instances using Mozilla sync.

Great experience! That was what I was looking for! Same functionality as the ones from Chromium based extensions. Thanks del-boy!
