Does the trick! I was holding the right mouse button and scrolling in the tab bar itself on my first attempt, as that was how an old TabWheelScroll extension worked. However the TabScroller requires you hold the button and scroll within the main page view window. Does a great job too - especially like the option to swap scroll direction. Good effort, cheers!

great replacement for a tabmix function!

I feel stuff like this should be defaulted into the browser. Too useful not to have.

Great! I did not expect it to be possible in Quantum.
