Thank you! This works just as advertised. TabWheelScroll was a must-have for me. I would've foregone using Firefox completely without this feature.

Didn't seem to work when first installed, but like another reviewer said it was because I tried it while hovering over the tab bar first instead of the page. The second because I was on the add-ons manager page, so I opened a few new tabs to check it out. Works great!

Works great, thank you so much!

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.
