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.

Great app, always helps me to save context for later

I love it but to eavy for my old PC

微妙。お試しで使ってみましたが、連続で真っ白画面で表示なしが3回ありました。これではタブが開けません。全部消えたのかと焦りました。怖いので使いたくありません。

Economise en effet de la mémoire ce qui est appréciable, mais les URL qui figurent dans le signet One Tab ne sont pas différenciés quand ils appartiennent à un même site (mais pages différentes). Difficile donc de rappeler celle qu'on veut.
Le "design" n'est pas non plus au top, ce qui est accessoire.

Un supliment surpriză pentru mine de care nu mă mai despart...

OneTab does what it says, but I wish it had the option of moving single tabs to the list instead of all of them at once.
