Restore all tabs not working

it lost my tab.
i have 400+tab ,when i add this addon to my firefox , it only get 100 tab . the others lost .

It was perfect till few months ago - now not so much. Crashes browser and worst of all does not save favicons. Had to remove it

I clicked the icon, it grabbed all my tabs automatically without asking confirmation. I tried to restore them, because it had closed them and added them to the list. When I clicked Restore all tabs, IT LOADED ALL OF THEM AT ONCE... I had several hundreds of them. It broke the browser, and I lost them all.
Not recommended at all.

CAUTION: I added OneTab to Firefox and don't want to use it. I want my tabs back where they were, but can't find out how to do this. OneTab has no function to delete it and restore my tabs. Why?

При восстановлении вкладок, восстановил только часть, а остальные пропали. Не пользуйтесь этим говном, если не хотите потерять свои вкладки.

I've been using this for a while. I have TONS of tabs saved in it. All of a sudden it doesn't work. When the tab that lists all my tabs could be seen, it was BLANK. All my tabs were gone. Right clicking on the icon in my FF's menu bar doesn't allow me to do anything. I can manage the extension only by uninstalling it. I can't reinstall it in hopes of it working and finding my stored tabs wherever it stores my tabs. On FF's page for this I can only uninstall it. I left a message for the authors of this extension but they didn't reply. It's ONE purpose is to save and not lose tabs. It lost ALL my tabs. I must have had over a thousand.

タブが復元されるのに時間がかかり、一部のタブは「新しいタブ」となり、正常に復元されない。

I loose all the links every time mozilla firefox updates and restarts. This is a serious bug which onetab team not fixed.

Lost my 83 tabs when I clicked "restore all".

Closes the tabs and stores the URLs. Breaks sites like Pandora.com

Despues de un un reinicio del ordenador por fallo del suministro electrico se ha perdido todas las pestañas guardadas en OneTab, no hay ningún backup no forma de recuperarlas.
Mucha información perdida

I love this extension until I lost all my saved tabs suddenly…
shit extend！

You not support Firefox Multi-Account Containers ?
I restore the tabs but the containers dont work i see ? ((((

no syn function. Be careful you will lose you bookmark one day.

One Tab needs a Dark mode option..

Who designed it so that all tabs disappear when the user clicks on the icon?
Why is it that when I freeze while restoring tabs, there are no tabs in Firefox and OneTab?

You will lose all of your saved tabs sooner or later. make backups regularly. Firefox/Chrome...doesn't matter. This extension seems great but it will break your heart and make your life a nightmare. After the first time, I gave them a pass and now I am screwed. Just because it hasn't happened yet doesn't mean it won't happen. Check out what they have to say about this app in Reddit. F**k me.

destroys all open tabs and the side bar add-on I had in use; worst extension I ever activated

[Update]: This app was good but keeps going down hill. After 5+ years, enough is enough. UNINSTALLED. The backup/export buttons have now been removed preventing any kind of tab integrity.

[Old Review]: Lost all my tabs, no idea why. This kind of unreliability is a problem. I have had it happen before, but it it is very irritating.
