When it works, I love it, but it often disappears and I can't find it again.

ENG / HUN: Be very careful with this: it archives everything in one click and without warning (!) - which means that if you use it a lot (for which Firefox is about the best browser), it simply takes an extremely long time to save!!! The reset takes approx. it's impossible because it starts filling up the tabs - with a huge memory requirement! I didn't have time to wait (any process), but luckily I saved everything before that with FoxyTab. That's what I recommend! I recommend that you 1. ask about it 2. write down the number of ears 3. give some calculation so that approx. how long does the process take 4. do not fill the tabs!!!
HUN: Nagyon óvatosan ezzel: egy kattintás és figyelmeztetés nélkül (!) mindent fület archivál - amitől ha sokat használsz (amiben ugye kb. a legjobb böngésző a Firefox) egyszerűen extrém sok ideig tart a mentés!!! A visszaállítás kb. lehetetlen mert elkezdi a füleket visszatölteni - óriási memóriaigénnyel! Nekem nem volt időm kivárni (semelyik folyamatot), de szerencsére mindent mentettem előtte a FoxyTab-al. Így inkább az ajánlom! Javaslom hogy 1. kérdezzen rá 2. írja ki a fülek számát 3. valami kalkulációt adjon hogy kb. mennyi ideig tart a folyamat 4. ne töltse be a füleket!!!

Have been using OneTab for years. Great extension, would love to rate it more highly, unfortunately there's too many usability issues. 1) I've just imported saved urls and because no feedback is given, I ended up importing the same URLs several times, and losing the latest open pages. No way to undo that, the "reject duplicates" is not active by default, and does not work retroactively.
2) I've submitted a request a long time ago, to select a group of tabs easily, and restore them all - not necessarily the whole group. Bulk delete should also be an option. Unfortunately, available options are very limited, and the extension has remained unchanged for a long time. Still grateful to the dev for creating something that should be native to any browser, but it really needs more work for me to give it more than 3 stars.

I am giving a 3 out of 5 (Down the Middle) The extension is amazingly fast to compile all the tabs into one tab but is excruciatingly painfully slow to restore tabs. Can this be fixed. Other extensions such as Tab Stash makes One Tab restore speed look like molasses in deep space. Hopefully there is a fix for this as I like the bigger layout in the OneTab screen. Thanks for your efforts though.

ich habe begeistert OneTab benutzt. Bis mein Firefox abgestürzt ist. Jetzt ist OneTab und alles, was ich darin gesammelt hatte, weg. Wie bekomme ich das alles wieder zurück??

I love it! It's simple to use, quick to understand, and makes moving between computer easy.
However, it's been like a week since it suddenly stopped working properly. It still saves all my current tabs when I press the button but the contextual menu doesn't work anymore. I have tried everything (even uninstalling and installing again) and nothing... Please, help!

É uma boa extensão, deve ser útil pra muita gente. Mas tenho poréns. Primeiro, o Mozilla tem a opção de "contêiner", poder usar contas diferentes em cada aba, e ao apertar no botão do "One Tab", as abas do contêiner são fechadas, restaurando só uma aba, então tenho que abri-las novamente, fazendo eu perder tudo o que já estava definido nas abas contêiner. Segundo, seria bom ter como minimizar as abas que são selecionadas manualmente, pra deixar de lado somente as abas que não usarei no momento.

I thought it was great until it disappeared, along with all of the tabs I had saved there, after my last Firefox update. No instructions as to how to get the tabs back -- it should be as easy as clicking a Restore button somewhere. And now I can't get it to work at all, though I no longer trust it going forward to keep all my info safe.

- It would perfect if they work with "Sidebery"-Adon
- "Miss reload page button" on OneTab Page if it is in laodmod for a fast relaoding.

after start firefox - button "onetab" in panel - show, but not worked. If disable and enable again onetab addon in firefox settings - botton begin work. After restart PC and start firefox - onetab button again non work.

nice onetap commits@roneroy

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

Хорошее расширение, даже думал поставить 4 звезды, но кроме отсутствия сохранения истории переходов (вперёд, назад) каждой вкладки (это минус первая звезда), обнаружилась другая проблема. В связи с тем, что OneTab автоматически НЕ делает резервные копии данных (отсутствует автосохранение), существует риск потери ссылок из-за ошибки самого расширения, которое периодически (хоть и очень редко) сбрасывает своё состояние в ноль. Это минус ещё звезда. Я уже не говорю про скудность экспорта данных (не хватает xml, json или подобного формата). В целом, расширение работает, но оно довольно ущербно.

yesterday i lost almost 4k bookmarks, for a first time using this addon for maybe year or more. didn't realize this could happen, so it kinda hurts. usually i did backups of all bookmarks from onetab after i reach certain point, 2-3k bookmarks or so, and delete them after from addon, but not this time. oh well. as a person below mentioned 'it good when it works', be careful, and do frequent backups

Sometimes you have to disable and re-enable the extension to get it to work.

Works as expected but not compatible with Firefox containers.
It is able to move all tabs into a list but when it restores them back, it is not in the same container!

Incredible how middle-of-the-road this extension still is after all those years of development...

MEMORY REDUCTION: yes, it can help you save memory... But a tab suspender does that equally well.

SESSION MANAGEMENT: well... VERY disappointing for that. On the OneTab Page you cannot move tabs to another window. You can't even rearrange windows.... Pretty useless for anybody who wants the tiniest amount of control over his "sessions".

When I re-install my system, the all web is gone...how to find them back? It's horrible.

Great Add-on BUT it stopped working several times and made the saved Tabs inaccessible.
No response from the developers. :((
