When I first installed Linux Mint Cinnamon, mouse scrolling in Firefox browser (ver 42) that came with it seemed really slow and jumpy.
After a little trial and error I managed to speed up scrolling quite a bit and make it smoother. Here's how I did it.
To speed up mouse scrolling speed in Firefox in Linux Mint Cinnamon. Also makes scrolling smoother and less jumpy.
(may also work in Firefox in other Linux distros, I haven't tested that, however.)
While running Firefox:
In the Firefox URL field type,
and press Enter.
In the Search field type,
mousewheel_system_scroll_override_on_root_content.enabled, default, boolean, false
to toggle it to true.
The line will now be displayed as:
mousewheel_system_scroll_override_on_root_content.enabled, user set , boolean, true
Click on the Firefox top menu
[X] Use Smooth Scrolling
This speeds up my mouse scrolling considerably in Firefox.
