I wish it worked.
Scrolling is excellent, I love the fact that I can flick faster by muscling the wheel, and it's pretty good, BUT it has too many things wrong with it.
Scroll boxes, some comments sections, text boxes, Youtube notifications, all refuse to scroll, instead scrolling the page.
I'm too used to the niceties of FFx to give up localized scrolling. Also, the bouncy edge doesn't render backgrounds, but renders elements, which is kinda ugly.
I don't know if there is a way to fix it. And since the dev didn't include a fast on/off (that I could find) I'm afraid it will stay disabled.
4/5 because it's a great addon, it works, and I like it. Unfortunately, no, thanks.
