Firefox Scroll Acceleration

Wednesday, February 24th, 2010 by | Filed Under: Using The Internet

The recently launched Firefox version 3.6 has a hidden function known as scroll acceleration which can drastically enhance your internet surfing speed.

Normally, whenever you scroll the mouse wheel the web page scrolls the exact same number of lines regardless how many times you might have previously scrolled it. However, when you have scrolled the particular web page a specific number of times within a brief period, almost certainly you are searching for something way down below or maybe above. This sounds like a case where scroll acceleration could be helpful.

Although it was implemented, scroll acceleration was switched off as it could’ve conflicted with mouse driver based acceleration. So it was postponed for next versions. However, the feature is actually there, and many users have already found it invaluable. Why don’t you also take it for a spin and see if it works for you?

To enable this, go to the Firefox address bar and type ‘about:config’. This will open up the advanced preferences. Now go to the filter box on top and search for ‘mousewheel.acceleration.start.’ Double click it and in the box that opens up set the value to 3. This indicates the number of successive mouse scrolls which will set off acceleration. Now, set the filter value for ‘mousewheel.acceleration.factor’ to 5. This indicates how many times faster you would like to scroll.


If the difference is not up to your satisfaction, try experimenting with different values and find the combo that works for you.

Find any difference in the scroll performance already?

Just a quick tip to perk up the good ol’ Firefox.
