Works. With vertical tabs it focus the tab above.

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

Yes

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.

Now is OK.

Great extension! Work perfect
