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.

The only bad thing about this game changing plugin is that I did not install it years ago!

It's great, but would be better if there is an option that makes left-click on the icon send only current tab to one-tab, instead of all tabs

Found it very difficult to remove. Tab to control it remains even after removing it in the usual way.

wake up people! awesome add-on espescially with porn...lol

Excellent usability BUT frequently consumes ~95% of CPU, therefore I can't recommend this add-on

Found out why OneTab wasn't working entirely by accident. Still disappointed by the lack of response from the devs. If anyone else has an issue with OneTab not loading, though, try this:

"I'd changed 2 settings in about:config

image.webp.enabled was set to false (default true)
image.http.accept was set to "*/*" where the default was "image/webp,*/*" - all without the quotes"

I found this for a seemingly unrelated problem with YouTube thumbnails not loading, but sure enough it also corrected my OneTab issue. No idea how the settings were changed in the first place.

Perfect! Does exactly what it's designed to do without a lot of redundant functions that other addons already perform. I use this in tandem with Session Buddy and Tab Wrangler to keep a reign on FF memory usage. This is an excellent feature in addition to them. It's function, quite simply, is to close all tabs (not pinned if you choose), and create a simple list of them all to be easily retrieved. YES, it opens it's own tab for this purpose. So what? One is better than a hundred. Saw that ridiculous complaint in one review. Don't listen to all the one star reviews. Almost all of them have no clue how addons work or their intended purpose. This does precisely what it's supposed to. Period.
