Change the Speed of Mousewheel Scrolling in Firefox
By Rick Broida
After the mouse itself, the mousewheel is the single greatest navigation tool ever invented. Mine is spinning constantly, especially in Firefox, where I use it to zip up and down Web pages.
By default, however, one “turn” of the mouse wheel scrolls only a few lines at a time–and I want to move faster. Fortunately, there’s a fairly easy way to adjust Firefox’s scroll speed. Even better, there’s a keyboard shortcut that can slow it down again for “precision” scrolling.
First, here’s how to change the default scroll speed:
1. Open Firefox, then type about:config in the address bar and hit Enter.
2. In the Filter box, type mousewheel.withnokey.
3. Right-click mousewheel.withnokey.sysnumlines and then click Toggle. This should set the value to False.
4. Right-click mousewheel.withnokey.numlines and then click Modify. Bump the value to 6 or so, click OK, and then switch to another tab to see if you like the scroll speed. (Thankfully, you don’t have to restart Firefox every time you make a change.) If not, experiment a bit until you find a number you like.
I keep mine at 7, though there are times when I want–or even need–the option of scrolling more slowly.
Solution: I hold down the Alt key. That drops Firefox back to line-at-a-time scrolling until I release the key. Can’t take credit for that killer tip: I read about it over at Lifehacker.
