Scrolling Fast With the Mousewheel Triggers History Back and Forth

Get Firefox

I’m observing an strange firefox behavior when I scroll the page using the mouse wheel. It goes back and forth through search history. So I googled a little bit and found that the KVM switch that I’m using it’s producing bogus key press event that firefox misinterprets. If you are running Linux the solution is simple as you can modify the X server configuration to ignore those events. But I cannot find a suitable solution for Windows.

Disabling history scroll in firefox (Usually triggered with Shift-) in about:config seems to have no effect in stopping this weird mouse wheel behavior.

Theorically changing the value of all mousewheel.horizscroll.with*.action and mousewheel.with*.action entries to 0 disables moving back/forward in history using the mouse wheel. Check this to know more about the meaning and purpose of mousewheel.* entries. But as I said It seems that doesn’t make any difference.

If you know the solution for this problem post it in the bug report.
