dont see the point of this extension, I can already do this by clicking scroll wheel and dragging mouse or scrollwheel. Seems that I am missing something everyone else is seeing, what is it?

changed my review, it was not fair to give low score for my lack of understanding what it does, but your faut too, for not being clear how it differs from standard scroll :P

Source is unreadable.

Very useful for people whose mouse suffers from mousewheel's scroll jumping problem after usage wear and tear.

Fantastic add-on, great options; I would like to suggest adding the ability to auto continue scrolling once the mouse hits the edge of the screen or default middle mouse click scroll

Just try it, and it will become your favourite.

not work nothing

Very useful as it's very customizable and native touch support is hard to discover in Firefox on Linux...
When setting the envvar MOZ_USE_XINPUT2=1 and the about:config setting dom.w3c.touch_events.enabled to 1, Firefox's built-in touch support is enabled and allows websites to distinguish between your finger and mouse pointer.

Good

I like this feature so much that I wonder if there is similar software for Windows, and I want to use it outside of the browser.

Hello! This is a really useful add on, especially when browsing with pen tablet. Although there's one thing that I think needs to be added. Could you create a new option to set how far the cursor needs to be moved after the scroll button is pressed to actually start scrolling? So for example, if the value for this setting is 10 pixels, that means the cursor wont scroll the page until the cursor has moved 10 pixels from its initial position. This will be useful for some websites like Twitter since it's very difficult to click anything there
