It work's, and then one day you will loose everything.

Even though this is one of the most useful add-ons (when you use it intentionally), it has caused me problems. If you click the icon once, even by mistake, it sends all your tabs into OneTab automatically. Then, if you try to reopen them, it opens and *loads* every single one of them in succession, causing a tremendous memory leech. AND - it loads them in reverse order! Now my last opened tabs are way left, at the other end of the row and I have to scroll back to reach them! Absolutely inconvenient and frustrating.

Vital!!

Very nice!!! Can you make a button to sort by domain?

Has worked well until recently, but now all my tabs are gone and I see I'm not the only one..oh, and their instructions for recovering lost tabs is a joke.

tout est perdu : nul !

OneTab Team, have you never heard of user-level queries or safeguards?
This add-on desperately needs them, and hopefully you're clever enough to figure out the rest by yourself.

OneTab has been around for so long now and it still feels like just a proof-of-concept type of add-on. It's missing options and features, and it seriously needs some kind of overhaul with a focus on performance when handling more tabs & groups.
