Sorry, The application works slowly, especially when switching between tabs and Panorama Tab Groups. This poor performance is since the fresh installation of this extension. It should be definitely improved.
I use FF Quantum 65.0.1 (64-bit) Portable version.

Useful, intuitive and stable ! Keep up the good work !

really love it. enjoy drag and drop.

I'm not sure how to submit a bug report, so I'll write a review with the low chance of this being seen. The actual tab switching and functionality works as intended and does perform well. My issue is with the screen with all the tab groups. If possible, don't allow for overlaying/overlapping of groups. This can make it difficult to find a specific group when one is covering up the other. Also for some reason, when switching between tab groups and viewing the main tab group page, all of my tab groups are stacked on top of each other on the upper left side of the screen. It would also be a quality of life feature if tab groups resized automatically and such kinda like how you can occupy 4 different applications in the corners of your screen on windows.

Two stars for effort but it doesn't work for me. When I click on the icon it opens up the tab groups, but all my other tabs disappear. There are no menu items or anything to move tabs into a group. When I first installed it a couple months ago it worked. Not sure what happened.

Has honestly revolutionized the way I surf the web! Thank you!

An excellent replacement for the old Tab Groups plugin. WOULD BE 5 stars but I just lost all my tabs AGAIN because I had opened another window with just one tab in it then closed my main window! The plugin only remembers tabs from the last window closed!!! Developer is normally VERY responsive for updates. Hope this gets fixed soon.

Definitely the best implementation of tab groups I've found so far for Firefox 59+! I haven't run into any bugs yet. It's only missing a few nice-to-haves, like smart placement of new groups.

I love it - except I am confused about one thing. I always have two monitors up, which means two *windows*, but tab groups can't seem to cross between monitors. I often move these windows back and forth between monitors too, so the organizational capacity is...lacking. Am I missing something?

Das wichtigste Add-ons für Firefox für mich.
