I thought this would be a great solution for all my tabs. I clicked the icon and watched all my tabs close. Then I got this error: Error code: SSL_ERROR_RX_RECORD_TOO_LONG

So it seems there are limitations that are not noted in the description. I have emailed the team for tech help, but am assuming my tabs are gone (even with recovery in place with Firefox, I could not seem to get that particular window of tabs restored). Incredibly disappointed in this add-on, and now instead of saving time, I am wasting time trying to figure out recovery. Lesson learned. :(

out of sudden stopped working.

Worked great. In the last month stopped working. Today lost all my tabs I had been curating. I will never use another tab manager that doesn't allow me to sign in to restore tabs in case of problems.

great add-on, ... until I lost all my tabs

I know it is probably not a fault of OT devs, but as you may have noticed, it breaks over time.

Suddenly broke. I'm not reinstalling to risk losing my tabs again - I'll find something more reliable.

Right now this add-on is unstable or bugged. The icon disappeared from Firefox and I couldn't use it, so I had to reinstall it to work again. Which resulted in losing all my previous tabs!
I hope this issue gets fixed soon.

Used to be great but now every time I open Firefox I have to go an manage my extensions turn it off then turn it on again. I don't know if this is the team's issue or a firefox issue, all I know is it is very irksome and I would like to hope it gets resolved

To those who also want to give 1 star review: addon now requires turning it off and on to start working again for some reason. Unforseen update of Firefox?

I've been using OneTab for the last four months and I loved it. I was now working in three projects with around 50, 20, and 15 tabs each. I was able to just group all of the tabs when I was not working in a specific project. I loved that I was able to name each group. But today, when I updated Firefox to the 80.0.1 version, OneTab did not reload my lists of tabs. It was just a blank page. I copied the URL, I restarted firefox, I also restarted windows... It did not help, OneTab was just not working at all. So I removed and installed the extension again. it works now, but it won't reload my previous lists of tabs. I have lost research work done during several months. I can't believe it.

Right now I am just trying to find an alternative.

Disappeared with all my data!!

Lost all my tabs in the last release. Tried all the fixes, turned off and on, and did a reinstall. Use the export feature to back-up my tabs, but it doesn't save the headers, or the starred order, so, more work. It seemed okay but today the whole add-on has disappeared? Very poor, have given up on this add-on. I'm using Simple Tab Groups instead, at least it works.

I lose everything in a moment. Installed on 3 of my 6 profiles, after restart the onetab tab show nothing and the icon button doesn't respond. I recover 2 of 3 profiles tabs with a lot of work.

lost,stop working,great.

well, this add-on was great... until it just stopped working and lost all my tabs. useless piece of garbage. I would have saved those tabs elsewhere if I had known this add-in was trash 🙃

Unfortunately became unusable due to the last update. Workarounds didn't work reliably for me and shouldn't be necessary in the first place.

Releasing an update in this state is a massive oversight.

Firefox crash one time and this extension stop working too. All of my tabs lost and there's no way to recover them. Is automatic backup really that hard?

All my saved tabs are gone and the disable/enable isn't working for me. OneTab just isn't reliable unfortunately, andnow I've lost months of research and work.

Loved this add-on up until the last 24 hours. The tab close on itself. When I tried to restore the closed tab nothing was there. NOTHING! Poof gone. Blank page. Oh, and this only happening on Firefox. All seem OK on Chrome. There is no back up or way to save anything when something like this happens (and this is not the first time). If you knew you're system was about to crash a heads up would have been FANTASTIC so we could have at least exported the URL. What gives?

*Thanks for your response, but that doesn't recover everything lost because of this "bug".

I've lost all my tabs! fack you!
A temporary solution for windows: go to C:\Users\XXXX(Username)\AppData\Roaming\Mozilla\Firefox\Profiles\2vl8majd.default\extensions and open [email protected] with firefox. Then reload the tab.
