A simple, well executed implementation of the original Mozilla idea. No fancy animations or tricks but still pleasing to look at in a functional kind of way. Reacts pretty much exactly as you would expect with resizing, drag-and-drop, etc. Very light on resources which is a definite plus. A keeper.

As so many have written before, I really hated when Firefox pulled this native feature. It was innovations like this that had kept me using Firefox as my primary browser. I tried living without the functionality and moving my workflows to what Firefox was a better workflow (pinned tabs, workspaces, etc), but none of them worked nearly as well. I often having several projects going on, with lots of tabs opened related to each project, so being able to intelligently change the context of Firefox to match what I'm working on is a huge productivity boost.

Anyway, thank you for this plugin that brings back this beloved feature!

One of the best extensions by far!

OMG, just what I needed. There was an old plugin which could not be continued because of changes in Firefox policies, I missed it so much!
Title of group can be changed with double-click on title.
A tab can be moved to a group with the context menu (right mouse).
A new group can be created with the + button in the "panorama" view accessible by the button in the menu at the top.
I did not find a way to move several tabs at once to a, but this is a minour inconvenience for me.

Finally, a workspace/tabs manager for Firefox that runs smoothly! Thanks a lot!

Exellent! So much helps to organize tabs' chaos. BUT (small but) after restoring tabs from backup, their order in each group is reversed. If the order is important, you'll have to rearrange the tabs manually. Please, correct it.

Perfect extension to organize my tabs. Simple to use, well designed. I recommend.

SO GREAT!!!! THANK YOU!

Omg, I dreamed for this extension and suffered in web since the old version stopped working in new versions of Firefox. After this I even tried different popular browsers to use, but no, all have different problems.
Thank you so much!

I *fear* the day this extension is no longer supported. I don't think I can browse without it anymore

Works as expected. Loved a differnt version of tab groups. Glad to have something similar back. Thanks

Here's hoping firefox re-introduces panorama view again, officially. Until then - this is a wonderful extension and works very well.

Basically I don't know what I would do without it.

Glad this one continued the now abandoned panorama view, which is honestly my only reason to stay on firefox, and this new design makes it even better, very easy to use and flexable for up to hundreds of tabs, best addon on firefox!

Exactly what I am looking for!!! I always have like 30+ tabs opened!! This solves my problem. I will see if this can also solve my PC memory issue. Just wondering if the extension actively cleans up those tabs that put into background to release memory ?

Absolute must have for switching work/fun context ;)
