This is by far the best tab grouping app available. It offers unmatched flexibility and customization compared to anything else on the market. Unfortunately, it’s been broken for months. Even when I manage to get it working temporarily, it often loses my saved groups or fails to restore them properly. The restore feature is inconsistent at best.

It seems Firefox updates may have caused compatibility issues, which is understandable, but I wish the developer had continued maintaining it. This app is leagues ahead of Firefox’s recent native tab grouping, which feels limited and clunky by comparison.

I’m holding off on uninstalling it because I still hope for a fix. The moment it’s stable again, I’ll gladly update my rating to 5 stars.
