I have the same issue. I use a Chromebook (ChromeOS 111) and the Lacros browser. It does wothe Chromerk with browser.

Thank you for your explanation. I think I understand. I'll play with it to get the grip.

Done, it was On. Hope it helps.

Hmm, now the tabroups stay there, even with other windows (collecions) open. There seems to be a consistancy issue somewhere.

I may have found the source of the problem: it seems to happen when other collections are opened in other Chrome windows. When there is only one window open, I can't replicate this behaviour. I keep testing...

I might have found the problem. I found out that in the cases where the Tab Groups disappeared, I had another instance of that collection open on another virtual desk. I checked: when no other instance of a collection is opened, the extension works great.

Yes, I mean the Google Chrome groups. I'll send you info by mail.

When I started using Tabox, the group feature worked perfectly. Now when I create or update a collection, the groups are gone. Is this a 3.5.6 related bug? I tried switching off/on the extension and deleting/reinstalling it. No joy.

I prefer it the way it is. I like being able to define my New Tab myself. A hot key to open the Tabox-menu would be fine, though.
