This is a really important addon for me and it is a desaster: After the last update all tabs are gone. >> There has to be some sort of backup for this - can you do it please! <<

For me the last update also broke this extension. All the tabs are gone.

The developer could have at least answered to one of the complaints and tell us whether only the GUI part is broken, but the information about the stored tabs is still kept somewhere in the profile (and if yes, then how to retrieve it), or all the information is lost completely.

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.

9-11-25: another "recommended" mozilla addon that is so unstable and only works well about 50% of the time. The rest of the time you're gonna wanna take a lot of coffee breaks waiting for this crap addon to load any list over 100 entries. Can't consistently load options properly or even load at all. No easy way to save entries that don't disappear with cache delete. no way to load entries across browsers. another junk
"recommended" addon by mozilla. why do these pretend developers waste our time with their learning how to code?
5-17-25:.stopped working on my brave browser with message to upgrade mybrowser.
4-1-25: has gotten extremely slow to load to the point of being unusable. Cannot handle large lists. system cache clearling results in your losing your tab list.Developer is no longer developing. Offers no way to easily save and edit tab lists. Share button is too close to import/export resulting in shares you did not click on.


5-2-23: Slow as hell. autoway to save tabs to backup file. Sometimes requires restart to get it to display the tabs. Another example of an addon with great potential that needs a developer that can deliver. Need to add auto save to addon.
11-25-22: what can you say about an addon that has such promise but comes up short. Does not work on epic browser-requires constant enable with each use to get the list. VER.Y SLOW in putting up the list on multiple browsers including ffox. makes your links into "SHARES" instead of just saving them like you asked. then you have to delete the share and make a new list again. buggy. inconsistent button implementation. No feature to saving your list, you have to do it manually. No user guide worth mentioning. Just another "recommended" clunky rather junky addon. better that bookmarks, but that's not saying much.
10-2-22 does not load with epic browser, won't work properly on most browsers, slow or unable to load it, requires disabling and re-enabling. Cannot save your links to plain text, cannot backup your links, another script kiddie addon from people who really cannot program.
9-2-22: THE MOST annoying thing about this "recommended" pos is that you constantly have to deactivate it and then reactivate it to get the dam POS to load the entries. A royal PITA to use it. Takes forever to load the entries and sometimes autodeletes them even when you set it to lock them. Like most of the "recommended" addons here, just goest to show how meaningless Mozilla's "recommendations" are. Lacks proper instruction and notice on how to adjust it's settings. Why can't "developers" write programs that JUST WORK???
8-1-22: The developers of this app are either lazy or not very competent. They hardly ever fix bugs, like your needing to deactivate and reactivate one tab to get it to show the saved tabs. No way to autosave your tab page. cannot set tabs to autolock so you have to do it manually each time. Another "recommended" addon that never quite works well.
6-25-22: Buggy. Won't load in many cases you have to disable and reenable it to get it to load and it's SLOW in loading. Should be able to "LOCK" site urls with a universal setting, now you have to do it individually. Slow to load, slow to work, the keyword is SLOWWWWW. Probably spyware, aren't they all? Save your urls manually has no way to do that from withing program. If the program loses them you are uked.
12-11-21 updates: auto opens second window without user input. cannot connect to tor as a result. Lost many tabs saved for no apparent reason. recommend you manually backup any important tabs. Have to disable it frequently to use tor or to prevent problems with it opening a second browser window w/out input. Needs work.

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.
