Works great! Thank you.

Thanks, my scroll wheel is broken but the button isn't, so this was really helpful.

Не е зле, но аз лично не виждам смисъл от тази добавка. В about:config правиш general.autoScroll да е 'true' и скролването с натиснат среден бутон тръгва. Което обезсмисля труда по тази добавка.
По-добре я направи да действа като настройката "number of lines" на мишката в Уиндоус. Там с настройка за 6 линии скролвам половината форум на Калдейта отгоре надолу с въртене на скролера, а не с натискането му. Само че Линукс потребителите нямат щастието да им е дадена такава настройка на мишката и затова мисля, че от тази добавка ще има по-голяма полза, ако се направи да работи като въпросната настройка в Уиндоус.

Чотко!

cool

Thanks for providing a "better than nothing" solution, but brace yourself, constructive criticism incoming ;)

- by default, we must keep the middle button pressed and move our mouse down/up, a lot, following which, after a delay, there is a brutal movement start.
Keywords: move a lot, delay, brutal.

- the "natural" movement one would expect would be that once the middle mouse button is pressed, the slightest movement up/down causes the slightest scrolling, while a stronger delta (my own non-techie term, the distance between "imaginary" pointer position and position of the pointer when we pressed the middle mouse button) will cause a faster scrolling
In a nutshell, there ought to be, both, no delay before the scrolling begins, and, imperatively (for it to feel smooth) a variation in the scrolling speed

- Lastly, we shouldn't have to keep the middle button pressed. More natural behaviour would be: we press it once. The plugin observes how much we move vertically from there and maintains a variable scrolling speed, maintained until we release it with a left.right.middle click.

I know, it's soooo easy to ask for all of that when you can't code an hello world. But, well, that's what was available before with XUL extensions, it's an ultimate goal, thanks already ;)

Pro's of this add-on:
1.) It gets the job done.
2.) It replaces the middle mouse button's purpose instead of just adding to it which avoids strange behavior.

Con's of this add-on:
1.) It doesn't scroll smoothly (about 3 lines of text at a time which gives this add-on a very clunky feel), and does not have the pixel level accuracy of other older add-ons that will become obsolete in Firefox 57.
2.) It doesn't give the user any control over what button should be assigned for scrolling.
3.) It doesn't provide a way to manage the copy and paste functionality of the buttons this add-on is replacing like older add-ons that will become obsolete in Firefox 57 do.

If your auto scrolling doesn't work on Steam, try this one!
