unrecoverably lost all my tabs when I x-ed out of the panorama view tab

It doesn't work. It does not show almost any current tabs nor windows. 1 star awarded for very good idea of visual representation.

Was good but now am getting issues like tabs missing from group when moving, unable to close the panorama window and being stuck in panorama mode. I have tried a few other panorama addons and, tbh, I think its too complex to maintain! Too many issues for all of them.

2weeks of work is almost wasted - i lost all groups...

I installed the add-on as a substitute for TabGroups. Initially it worked fine. Not quite as convenient as TabGroups was but absolutely fine for the start. But then all the groupings I created disappeared. Opening the overview showed 1 tabgroup and not a single tab. I deactivated the add-on and all my hidden tabs reappeared. After enabling the addon again (or deleting and installing it even), the overview does not open anymore. Neither clicking on it nor the shortcut do anything. I use the most recent version of FF (just check for updates). Once provided with a solution I will move up my review to 4 stars.

Great features to add would be the following: Going to a tab outside the current tab group by typing in the address bar = search mechanism, moving tabs more easily without needing to go into the overview,
