Works great. The only issue I have is the options don't seem to persist on browser closure. I have it set to sort automatically but each time the browser is closed I have to select the sorting option I want.

Amazing, easy to use, jut pin to toolbar

Works great! However, does not seem to work in Private windows, would be great if it was fixed.

Does what is says. Pretty useful. It's no longer in development I think but I wish it also did:
-Custom sorting (e.g. "put example.com tabs at the start regardless of alphabetical order")
-Sort by container tabs

sometimes does not work but anyway it is a good add-one

Unfortunately does not seem to work in private windows (yes, I have allowed it to 'Run in Private Windows').

Update: I still love and use this addon. However, it needs to be made compatible with the new Firefox tab groups. When sorting, all tabs get removed from their groups and the groups are discarded.

Original review:
Way, way better than SortTabs. It is incredibly faster when you have a ton of tabs (I regularly have over 1,000 tabs as I study a ton) and does not have any intrusive required permissions–just access to browser tabs and that's it!

Love it.

Nice add-on, but does NOT 'sort by URL'.

"Sort automatically" does not always work. If this gets fixed it's a 5 star addon!

Great app! I'd love if it was possible to have the sort menu also appear in the right-click menu on tabs.

It works fine, but for some reason, it does not remember the setting when firefox closes, each launch, I have to 'refresh' the setting. Other than that, it works.

Like it, but could you add keyboard shortcut, please?
