Пользуюсь во всех браузерах. Нет резервирования списков - приходится делать это вручную.
В Firefox 80 периодически "пропадает" OneTab - приходится идти в меню "Расширения" выключать и снова включать OneTab. Несмотря на многолетний стаж расширение недоработано, на мой взгляд. С первого момента его создания, сколько бы оно не обновлялось, не вижу никаких улучшений. Жаль, что хорошая идея не реализована в полной мере.

A very good addon until the last update. Now I have to disable and re-enable it each time I open firefox to get it to work.

Je trouve cette extension vraiment bien MAIS elle se désactive systématiquement à la fermeture du PC!!! bref si ça continue je chercherai une autre application. Décevant

Giving this a 3 star because its a great product, however their latest update really botched everything. For people looking for a permanent solution unlike the disabling it and re-enabling it (only works until you restart Firefox), you can first back up your tabs using the methods many other reviews have outlined, then scroll down the OneTab page to the More Information section. Here you can click on the link to previous releases, uninstall OneTab and then install version 1.29 and restart Firefox. You may also want to disable automatic updates in the extension settings so it doesn't update again, and this WILL clear any tabs you have loaded in it, so remember to back up the folder before restoring it afterwards. Hope this helps and doesn't get buried instantly.

all tabs gone, disenabling and then enabling the addon again resolved the problem

I lost OneTab button on the top left of the window and in addition, the tab list page displayed nothing.

I turned off (not deleted) OneTab, restarted the firefox, and turned on OneTab. Then all came back in my case.

Also, URLs of the tabs seems to be written in extension@one-tab.com, which is a subdirectory (subfolder) of the directory (folder) of firefox or mozilla.

I'm glad if this helps you.

This is a must-have extension for avid Internet users. The problem is that the recent update caused the extension to stop working, and I lost all my tabs. It seems that many users suffered the same thing.

I'm also a developer and I just can't imagine shipping a new product version that breaks everything so drastically.

Lesson learned. Never depend on any tool. Tools can be wonderful, but you never know when they are going to break.

I will rate with 3 stars because addon developer created this addon. If mozilla made this add-on then I would rate it with 0 because it doesn't even deserve a rating of 1. I am still using Tab Groups because groups are totally hidden and I can backup all groups and tabs with just a few clicks. In less than 1 minute I have 100+ tabs on my laptop.

What I need to do is foud a developer, then pay him to hack Firefox version 54 and change it with latest firefox version.

Latest firefox versions is totally the same as any other browser -> GARBAGE.

100 tabs use only 1 GB of ram :D why do we even need x64 if browsers are NOT even created to run more than 10 tabs!!

Running 50+ tabs without Multi-row no thanks!! I will not have my tabs in second window, because Multi-row do the job perfect and I can see tabs names without clicking on anything!

I like browsing fast and with less clicks and not with more click to do the same!

For example new sidebar oh my good!!! By default sidebar on the left side and icon for open/close sidebar on the right side :D :D :D Every time moving the mouse on the entire screen :D do they even have brains??!

works great but why does it need permission to access all my data from all websites? Disabled.

Esta mas o menos bien

Leider kein Dark Mode, da bekommt man ja Augen-Infarkt beim Umschalten.

Je ne trouve pas comment régler l'extension sur firefox (en cliquant droit sur le logo de l'extension) alors que c'est possible sur chrome. Arrangez ça svp.
Sinon pour régler les options il suffit de cliquer sur le bouton de l'extension et une page s'ouvrira...

I suspect this is slowing down my start-up time but I have no way to check how

Usability wise and task wise: it is to the point and does exactly what you want it to do.
Accessibility wise tho? Not so much. The only thing that would make me bump it up to a 4 or even 5 star review would be if the tabs could be synced to other devices or to your Firefox account you use to sync tabs and the such. There have been many cases where I had to clear cache because something was acting up or my cache was just bogging up space and lost my tabs as a result of said clear.

TL;DR Crashes Firefox = lost tabs -
Using Firefox on Windows 7, the intended feature works well however, it causes Firefox to crash every 1-4 hours. It does not crash on execution, nor depending on the number of tabs open. This bug would be alright if Firefox would then load the previous windows/tabs like it usually does upon reopening... but something about the crash causes the last window you were focused on to be deleted from memory. It doesn't load on reopening (other windows will) and "history" rarelyy has record of it. (Sometimes you can just go history -> closed windows and reopen but typically there are no "closed windows" listed in that list.) I'd give this a lower rating if other "session manager" add-ons were available for Firefox the way they are available for Chrome.

Works as intended with one very annoying "feature", whenever you open your browser the one tab page auto loads after a delay of few seconds and steals the focus from whichever tab you were previously on. So if you open your browser to quickly go to website or to google something quick, while you are typing in the address bar suddenly you get switched to the One Tab page. I would prefer if there was a option in the settings to disable this so that you can open the one tab page only when you want.

It's OK. as long as all of the tabs are loaded in Firefox (not asleep), this extension will suspend them to the mobile browser; for this I'd recommend a feature that refreshes all Firefox mobile tabs, if that is possible. My one biggest gripe is that it is lacking many features from the desktop version, such as the option to not open onetab at startup. Please add these, as it is really annoyong having the onetab page pop up whenever I open a link in Firefox.

firefox android. приходится несколько кликов делать. 1.открывается окно onetab. 2 нажимаем отправить все вкладки в onetab. лишнее действие, имхо.
и отправит не все. только часть активных, может вообще 1 вкладку из сотни. зато закроет все вкладки.

Neat app. But couple of issues.
* No Darkmode, despite my firefox using dark theme. No option in app for choosing it.
* Sync ability with firefox account or any cloud option.

it would be so much better if it was like the chrome

I used to have this Addon on the Chrome Browser. Now I tested it yesterday on Firefox. The only feature that this addon is lacking, is the <> to find Tabs Quickly. And the ability to separate Tabs into several Groups. For Example: YouTube Group (with all the video tabs), Design Group (tabs for design websites), etc...
Because I have more than 1000 tabs open So I can not find easily what I want. I will update my review when They add these two important features.
