As far as I can tell, this extension is irreparably broken.

My previous experience with OneTab had been fantastic! I was able to cache tabs I wanted to keep and come back to them later, even name and organize groups of tabs based on personal categories. It was great! But sometime in the past few months, the extension no longer loads properly: when I open the tab list, it shows a line of pulsing dots indicating that it's loading...but it never loads, no matter how long I wait for it.

I've tried closing and re-opening Firefox, shutting down and restarting my computer, disabling and re-enabling OneTab, disabling every other extension I have, even removing and reinstalling the extension, and nothing changes this lack of response. After losing every tab I had open because I accidentally hit the OneTab button and sent all of them to a window I can no longer access, I'm finally writing it off as a complete loss.

This was previously a great extension, and I hope that someday it will be again. But until then, I'm sad to say that it's not what it promises.

Resource hog

after start firefox - button "onetab" in panel - show, but not worked. If disable and enable again onetab addon in firefox settings - botton begin work. After restart PC and start firefox - onetab button again non work.

nice onetap commits@roneroy

Upon install and clicking the icon, automatically closes all tabs and puts them in the list. When selecting to restore tabs, it opens them all as "refreshing" instead of "discarded", so if you have hundreds of tabs, it will end up crashing your browser.

Works perfectly; frees up space on my browser and helps me regain focus. Fantastic!

Very useful - would be better if you could move multiple tabs at a time within the lists, it's a pain to sort them one by one

horrible extension, lost all my tabs while trying to figure out how the addon works

firefox crashed and i lost all the tabs😭

Installing this was an immediate disaster for me. When I tried to save a list of tabs from one window, instead OneTab immediately closed the window, saving nothing, and I lost all the tab locations. It also inserted its own pinned tabs into a few windows that I hadn't even opened, and screwed up a couple of other things. Removed.
