keeps track and saves your search history such that it's easy to look back and find what you were seeking b4. However very annoying as it opens without input from you everytime u open ur browser and then you must close it. Delays your browsing due to this.

If there are any Private Browsing tabs open, activating OneTab will add only those tabs to the list, while permanently closing and discarding all of the non-Private tabs.

I've had A LOT of tabs. I'm kind of a tab hoarder. So when I've discovered that Firefox on Android changes the tab number into infinity sign I felt a bit accomplished and also depraved of all surfing morality.
But I've also felt like I was kidnapped by that situation, so I wanted to fix it. Get it all into OneTab like I do on my desktop and sort it a bit.
The add-on only added the newest and active tab. My whole backlog is gone and you've let me down in the most crucial of moments. :(

Bookmarks but a bit quicker. Unresponsive to questions sent through official channels.

Firefox version needs some work; auto-load on startup is slow, and doesn't work in incognito.

Auf meinem Android Tablet verschwanden beim klicken auf Onetab fast alle meine Tabs ins Nirvana... Verwende Onetab auch am PC dort hatte ich nie Probleme. Also Daumen hoch am PC Daumen runter unter Android.

Just installed this and lost all my tabs, by trying to restore and "one tab" again too quickly, so that not all of the restored tabs were loaded yet. Those that weren't loaded weren't "one tabbed" so I went from 17 to 5 in 1 second ... Can't remember all of them and was researching for an essay, so that sucks (: But I appreciate the idea and hope that the developers can maybe include something like waiting until all tabs are loaded, before allowing a user to use this feature.

Firefox recommended a "Reset" of the browser, which created a "Old Firefox Data" folder on my desktop containing a backup of all of my profile data — including extension data. I have tried restoring my OneTab extension data (links/URLs) using Firefox's restoration process, but OneTab is the only extension that does not seem to restore its previous data. I have contacted OneTab through their form on their website twice and have not heard back. I would pay for support at this point, but it's unfortunate I am dealing with potential data loss with no answer from the developer. Again, I would compensate the developer to assist in helping my current situation. If I am able to restore the data, I will update my review and increase my rating.

The Android version is not well adapted

It is far better than browsers native bookmark features. However there is quite a bit of resource usage during normal browsing (not when sending tabs to onetab or loading onetab tabs) according to firefox's task manager. It clearly isn't just jotting down URL's when you press the button which is both a privacy and performance concern.
Also if you restore tabs from onetab too fast (and have it set up so tabs are deleted once restored) you lose tabs.

On firefox for android, only saves tabs that are in memory, but clears all tabs. So say you have 100 tabs and only looked at 3 recently. Using OneTab will save those 3, and close the other 97 with no way of getting them back.
Note to developer: only close the tabs you successfully saved. That will fix this problem.

Does not work in private mode. Ate all my tabs, unrecoverable in normal mode.

FF is 68.0.1 on Windows 7.

Aug 9 - UPDATE
Additional info - there MIGHT be an incompatibility with another addon. During troubleshooting, I found that I also had Auto Tab Discard addon enabled.

I recovered my tabs, disabled that addon and now OneTab seems to be working okay, but it does not recover private mode tabs back into a private window. It restores them to a public window. :-(

At a minimum, private browsing is not working as expected.

And if the 1.29 release was just a repackage of 1.28, why is it a DIFFERENT size than 1.28?

Used to work in incognito (5 stars if it does), but now when hitting the OneTab button all tabs vanish and won't show up in the OneTab page

I LOVED this extension so much and relied on it for so long, but the recent update cleared all my saved tabs and I don't know how to get them back! Please help

The extension is unusable if you try to save a reasonable number of tabs (say, 200-300) at once. When this happens, the extension eats 15 GB RAM and 100% CPU and caused Firefox to become unresponsive forever. After fifteen hours of waiting for the tabs to be closed, I had to kill the browser. After restarting the browser, all the tabs I tried to save were still open. This is not acceptable.

Это тридцатикратно ебучее говно уничтожило после обновления больше двадцати тысяч моих вкладок.
UPD. Комментарий (на английском) о том, что можно откатить назад я, естественно, не увидел.

I absolutely LOVED this extension! That is until it LOST ALL of my tabs!! 😡 I would literally PAY for syncing capabilities.

Sorry to burst your bubble Perce-Neige, but OneTab most definitely does lose the tabs. I've been using it for a couple of years, and have gone though multiple crashes with no problems -- until today. Firefox crashed, and when I started it back up OneTab was empty. This is unacceptable! OneTab should make a backup when Firefox closes (not crashes, but closes), and it should NEVER overwrite a file, even if corrupt. Two stars, and looking for a replacement.

It works when it wants to. But randomly, even between sessions or reboots, it forgets the 400-odd tabs that had been imported or saved into it. It has done this multiple times on both Chrome AND Firefox, and I will be taking my volatile data elsewhere.
Good day.

Serait parfait si effectivement ça réduisait la RAM... ce qui absolument pas (plus?) le cas
