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 .

Excellent..., Excellent..., Excellent...

es muy buena

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.

super tool!

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.

I don't normally write reviews, but this has been super useful for somebody like me, who likes having lots of tags, but also values organization. I use it to switch between my 'working' tab groups for each of my college classes

Bookmark icons disappeared after browser update.

A must have when doing research.Easy to use too.
