Recently Firefox added its own tab grouping feature that could synergize really well with this extension, but unfortunately there's a bug:
When you create a Firefox group it also creates group collapse button for it, and when you switch to another STG group, it hides the grouped tabs but not that collapse button.
Hope it gets patched, because it's a bit janky and annoying.

отличное расширение

In the past week or two I keep losing all my settings for this. I did (belatedly) create a back up .json, however even that, as of today, is not being recognized as valid...

Hoping this is seen and dev, or other users, can offer insight, as this is one of my most valued extensions.

Cheers 🍻

With that being said, I love the add-on and appreciate the QoL improvements it brings to my internet. Can't imagine not having it at this point.

This is THE tab manager I was looking for in Firefox. It took a bit to adjust and I thought I preferred the tab grouping I've used in chromium based browsers. But this is so much cleaner, easier to organize and reason with, and maintain a solid separation of concerns with tab grouping.

Exact what i needed, the best!

Un module vraiment essentiel pour Firefox, un grand merci aux devs !
Ca serait super qu'en complément de la nouvelle MAJ Firefox des "tab groups", les tab groups soient propres à chaque groupe du module. Par exemple, si j'ai un tab groups "réseaux sociaux" dans mon groupe "privé", j'aimerais ne pas le voir dans mon groupe "travail", plutôt que de voir un tab groups vide.

Fixfox devs should have taken inspiration from this extension instead of copying chrome groups. This extension is truly life changing.

Perfect. The best.
Please make it for Chrome too.

Lots of useful tools to organize tabs far better than any system I,ve come across yet.

Life changing, thank you Drive4ik for making this, I had terrible habit of closing and reopening tabs, this really helped me just keep things organised, really grateful for this!
