Leider werde ich OneTab nun löschen, nachdem in der Vergangenheit mehrfach meine gespeicherten Tabs verloren gegangen sind.
Schade.

Was glad to come across OneTab, an answer to an urgent need for something like it. My lightweight Dell 3350 laptop, running Linux because Win 10 is far too demanding for more than one tab, is quite capable of handling the 60 tabs via OneTab.

Great work developers!

However, I cannot see how to organise the tabs

good extension

I don't see why it may be useful

A simple, convenient and dare to say elegant way to group tabs either to save memory or to save for later 👍

I consider this addon ESSENTIAL. It is well-designed and just works! To use it is to love it!

Great features that really helps.

Sooo helpful for keeping organized. The only wish I have is that we could search our lists of saved tabs; I'm getting an updated version here and hoping maybe that function has been added.

Even without that, though, it saves slowing down my computer from multiple tabs, and allows me to compile research sites.

I had 500+ tabs and did the mistake of clicking this extension. I have another extension (Panorama View) which grouped them, but OneTab discarded all of that. I tried reopening them all, but Firefox crashed, and after restarting it, all of my tabs were gone. Oh well.
TL;DR: I lost every tab I had.
