Wow surprisingly good on Ubuntu-MATE 19.10/ FireFox 73.0
I am already addicted. Also with the default setting it does NOT remove the paste with the wheel (I was scare about that so it was the first thing I did tried, and got very happy), Excellent!
I like also your humor in the setting page (1000 grams, it's funny;) )

Very nice add-on, thanks-thanks a lot!

Works like a charm! Beats the hell out of using the mousewheel.

Hello, thank you very much for making this extension!

However, it's almost unusable for me. The extension has no threshold/delay (see, Gesturefy extension) for when scrolling should begin so this issue makes right-clicking links (for example) prone to accidental scrolls of the page. There needs to be a customizable pixel threshold else the only semi-valid option for me is using the middle-mouse button (which still has the same issues: middle-clicking links), as this is not as commonly used to interact with the browser. The threshold/delay option should affect all three modes middle-, left-, and right-click. I'd highly appreciate adding this threshold option. I was actually surprised it was not already included! It seems necessary for a more error-free experience.

Thanks!

does not work with embedded frame scroll bars, for example on monster and linkedin pages

totally good, but laggy scroll with some sites (twitter etc.) and scrolling speed is not same each page

Nicely implemented. It is however kinda annoying from time to time since just the slightest movement prevents the default button action from firing. I really wish there is a minimum drag threshold option, otherwise right click doesn't fire if moved slightly, or double clicking when it comes to the middle button.
