How to Change Firefox Mouse Wheel Scroll Speed?
Xah Lee, 2011-05-30
- ① In the url field, type
- ② Scroll down to “mousewheel.withnokey.sysnumlines”. Double-click the line to set the value to “false”.
- ③ Double-click the line “mousewheel.withnokey.numlines”, and set it to a number you like.
The change is immediate. You don't need to restart Firefox. This works in Linux too.
In a similar way, you can get mouse wheel to scroll one-page at a time. You can also adjust the mouse wheel tilt to do page up/down instead of horizontal scroll.
Set Mouse Wheel To Page Up/Down
- ① Click on “mousewheel.withnokey.action” line.
- ② Set the value to 1.
This will make the scroll wheel to go by pages.
Here's tech detail, from the official doc at http://kb.mozillazine.org/About:config_entries.
These fall into two groups: vertical and horizontal scrolling. The general form is:
- mousewheel.‹modifier key›.‹type›
- mousewheel.horizscroll.‹modifier key›.‹type›
The ‹modifier key› key is one of: “withaltkey”, “withcontrolkey”, “withmetakey”, “withnokey”, “withshiftkey”
Type is then one of: “action”, “numlines”, “sysnumlines”.
integer value that determines the type of action:
- 0 - Scroll document by a number of lines (given by the numlines property)
- 1 - Scroll document by one page
- 2 - Move back/forward in history
- 3 - Make text larger/smaller
- 4 - Scroll document by a number of pixels (given by the numlines property)
number of lines to scroll by if action is set to value 0, or pixels if action is set to value 4; otherwise, this value is ignored.
use system preferences to determine how many lines to scroll by
