After using it for months/years, I lost a whole lot of unrecoverable tabs.
With no warnings at all, yesterday it deleted all my tabs information and now I can't recover it :(
To quote another user: "Second time I am losing a whole lot of unrecoverable tabs.
And usually when I don't like something I just uninstall and move on with my life. But this time is different.
I feel like I have to WARN people because OneTab fails to do so. If you have a sub-par extension, either fix it(automatically backup? support recovery?), take it down or include a Disclaimer that your extension should be used only for casual usage.

Because anyone who actually wants to keep their sh*t should definitely STEER AWAY from this extension."

useless....

No brainer - now on Firefox and Chrome. Hope to see it on Opera as I test all browsers.

So simple and deeply useful. Either when I'm doing a bit of research and collect a pile of tabs open, or when I am flitting about between several different topics. Why isn't this a core feature of the browser?

simply the best

老用户了，必须支持

Very simple and effective idea to better organise your tabs, thanks.

Cool!

though I love the app and it actually did what it said.. Though I think one thing that should be added that will be also easy to implement for oneTab is to let user add a description for the link they have just added to their one tab list, which makes it easy for user to remember anything if he wants to save about that url .. something like notes

It is simple to use, doesn't get in the way, the developers' website is clean and pleasant to read. And the developers aren't asking for money or even registration. Almost perfect.

Works but buggy for example it doesn't pin and also doesn't stay where it should be in the tab order. Doesn't work at all in Android Firefox

I lost all my tabs after launched this extension.

Bonsoir, Très pratique extension, malheureusement j'ai dû retirer 1 étoile suite à de nombreux bugs suite auxquels je m'estime heureuse si tous les onglets (leur adresse évidemment) ne partent pas tous ! Ce qui m'est déjà arrivé à bien trop de reprises dont la dernière en date d'il y a 2/3 jours... J'avoue qu'à ce moment, je peste ferme contre tous !!! Le jour où ces bugs n'arriveront plus, la 5ème étoile sera placée au plus vite.Si vous aviez le temps de rectifier ce qui ne va pas afin que cela n'arrive plus, je vous en serai immensément reconnaissante, soyez-en certain. Je vous remercie déjà du temps que allez y consacrer; à défaut, après un délai raisonnable, je me verrai dans l'obligation de choisir une extension plus fiable, et ce, même si la vôtre est plus pratique. Je dois pouvoir me fier aux extensions que j'utilise quotidiennement, j'espère que vous comprenez ! Je me permets de compter sur vous. Je reste dans l'attente d'une réaction de votre part ...

links' icons are broken.
If a lot of tabs saved, loading onetab page is slow.
It would possibly lost all of saved tabs.

And now there's an better alternative (and is FREE SOFTWARE)(and don't require "Access your data for all websites").

EDIT 12/24/2019:
Can't work on Firefox Android at all, all my opened tabs lost but only that poor 1 is saved!! If you can't do it, then don't make it available on Android platform!! What a garbage

よく行くサイトをまとめて登録しておけば、非常に簡単に行けるのがいい。
ブックマークと違ってトップページ以外でも細かく指定できる。

Firefox 67 диспетчер задач показывает что addon OneTab сразу после запуска браузера и открытия его страницы с сохраненными вкладками (1800 шт.) потребляет 28 Mb.RAM, вкладка со списком 8.5 Mb
Это же очень много !!!
Его альтернатива - "Tab Session Manager" потребляет всего 593 Kb !!!

Автору надо серьезно задуматься об оптимизации, а может доучить JS.

Сама концепция интерфейса меня устраивает и может она даже лучше чем у конкурента, Но неплохо было бы добавить опциональное сворачивание списков.

PS: Надеюсь автор это прочитает !

Really reduces tab clutter by letting me keep track of groups of pages without creating a bunch of bookmark clutter I have to manually clean up later. Switching from one research task to another is fast and smooth.

It deleted all my tab information and now I can't recover it :(
