I have ported the good old Tab-Groups to FF dev 81.

https://github.com/117649/Tab-Groups

Work in Progress state. No way to move opened tab to another group by right click on tab (or anyhow?)

I'm still trying it... early on i felt i had found all i needed to organize myself but not so sure now... no secured way to transfer tabs from folder to folder or to know if the folder u are one is the right one

Really love the clean UI; would love a way to select tabs and move them to a new group. Thanks!

edit: wait I stand corrected; while you can't drag a tab to a new group, or right-click and send it, you can click on a tab while in the group you want to transfer to, and it'll open there, and then close the tab in the original group.

Need an improvment on the animation theme

1. When the group is changed, the browser restarts. That is how it should be?
2. When adding a group via "Add new group", the previous current group is deleted. What am I doing wrong?

Thank you for starting work on this add-on. Successes. Surprised that so few reviews.

This looks very promising but it desperately needs tab hiding for it to be usable (upstream limitation I know).

1. The addon is not represented in the search! Why?
2. When you open a group of tabs loads all!! tabs group. Why?!
3. A very useful addon. Judgment on the number of users of the old version.
4. Thanks for starting to do this work. Successful implementation!
