I like the app, but there is a nuance.
I cannot select specific tabs and send them to OneTab, there is no "OneTab" item in the context menu of the tab. I have to move the group of tabs to the end, select the previous one, right-click on the add-on icon and select "Send tabs on the right...". Very uncomfortable.

Reinstalled firefox. All my other plugins' options got synced and restored seamlessly, but i seem to have lost all of the tabs I had in this addon. I understand that this data is stored locally only, but it would have been nice if there was backups or something built-in.

Very useful extension! Has been very reliable and saves me from constantly emailing links to myself to "visit later".
Suggestion: Would be wonderful if you could specify which open tabs should be added to OneTab, as opposed to sending ALL open tabs to OneTab.

A lot of us want a button to send one tab to the list instead of all the active tabs

Really great for briefly reorganizing or saving some tabs for later. It's not for long term storage, and shouldn't be used for that. My only complaint would be that it doesn't have a dark mode, and it seems to be immune to Midnight Lizard, so I'm stuck with a white page. There might be a way to fix this with custom CSS, but dark mode kinda should be built in by default.

noticed a bug, file:/// links are saved, but as soon they are opened they are removed and not opened...can't contact anywhere except here...will give higher rating if bug is fixed

Easy to use and get used to. Though, I wish it had a dark mode setting.

Very nice

Disculpen, pero seria bueno poder ordenar los enlaces cuando estan en el onetab y poder marcar aquellos a los cuales uno cliquea para abrirlos en una nueva pestaña del Firefox

Monochromatic icon for dark and light themes are needed. Please some automatic backup should be there.

A very nice and useful addon, but that white kills the eyes. Please add a simple color chooser for both foreground and background, please.

Information about container is not stored. Tabs aren't restored in container tab like work/media/shopping/…
Missing search/filter input box.
