Não pede confirmação para remover todas abas atuais, para agrupar em uma aba/página com os links. Deveria ter essa opção de configuração, inclusive a confirmação para realizar esse processo de agrupar os links de abas em apenas uma aba DESTACANDO que as abas serão fechadas.

DO NOT INSTALL THIS. It will delete all of your tabs, with no way to recover them. Check the other reviews, this is happening to everyone.

Don't use it, it's very great at first and then it will lose all your tabs. Twice.

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.

Have lost all my saved tabs multiple times after my browser updated. Do not recommend at all.

lost all saved tabs after a browser update

Leider werde ich OneTab nun löschen, nachdem in der Vergangenheit mehrfach meine gespeicherten Tabs verloren gegangen sind.
Schade.

I don't see why it may be useful

I had 500+ tabs and did the mistake of clicking this extension. I have another extension (Panorama View) which grouped them, but OneTab discarded all of that. I tried reopening them all, but Firefox crashed, and after restarting it, all of my tabs were gone. Oh well.
TL;DR: I lost every tab I had.

stopped working after the last firefox update. The support team does not want to help much. Very upset

This app is totally useless and a waste of space. When you go to look for your tabs, half of the time they're missing anyway. Why doesn't Firefox change the settings instead and not allow sites like Ebay to open 50 million windows every time you look at a listing. The multiple windows never use to be a problem, so maybe Firefox needs to address this issue so we don't have to have useless apps like 'One Tab' taking up space on our computers just so Ebay can open another, and another, and another window that will be wasting up space in the 'One Tab' app.

Sketchy privacy policy. Use Tab Stash instead.

Absolute garbage program. Lost all my tabs after just a period of days having it installed. Found people reporting these same exact issues going back to 2017. Tried solutions and while I was able to recover almost everything, this is too risky. Can't believe it has such high ratings. Avoid at all costs.

Cannot imagine... It CLOSED all by tabs. Without asking me. I expected it helps me but it destroys everything!!! Do not recommend it. Such a behaviouur of extention is definitely not smart

The add-on somehow deleted my saved tabs after restarting Firefox.
