Tut was es tun soll. OHNE unnötige Berechtigungen zu verlagen. Extrem gut.

Yes

Works good, except that I have to uninstall and reinstall each time I start/restart firefox.

Make firefox OBEY customers again.

The extension doesn't work at all for me. Running on Firefox 122.0.1 (64 bit version).

just started using it , works fine need more of these hard to find.

Works for me with Firefox, 89.0.2 (July, 2021)

Thanks!

Works great and does exactly what it says it does.

Really natural and smooth tab transitions, no other addon can be like this.

doesn't work after wake up from hibernate

Now is OK.

Doesn't work with LTS

It does not work... it worked once but no more.

Does not work for me either. Correction... it worked once, then no longer.
This is a shame as it's something that should be built into Firefox.

Doesn't work reliably. When works, results in noticeable flickering(*).
(*) I suspect that it's because it allows "default" tab selection to be done first.

"Select After Closing Current" seems to be a better choice: works reliably so far and flickering is less(*)
(*) though it also seems to be not able to completely prevent default tab selection

Doesn't work! Enabled and Disabled works for a couple of minutes then it quits! Had hopes but alas it doesn't!

The positive reviews must be relatives of the developer.

Funktioniert leider nur in 9 von 10 Fällen (wenn z.B. ein Tab im Hintergrund geöffnet wird und der aktive Tab geschlossen wird geht er manchmal nur zum rechten Tab).
Das Add-On wechselt genau so wie bei den Konkurrenzbrowsern erst zum rechten Tab und springt dann in den linken.
Einziger Browser der das nativ ohne Add-On kann ist vivaldi dafür staucht der FF aber nicht die Tableiste bis ins unendliche.

Ich denke nicht das ein Add-On diese Funktionalität je besser bewerkstelligen kann als jetzt da der Unterbau es einfach nicht zulässt.

Сделайте чтобы просто переключалось на левую вкладку при закрытии. Не нужно открывать правую вообще.
