text: why won't trackpad scrolling work in firefox on hp zv6000 laptop? scrolling works fine in ie and all other apps, but not in firefox i have the zv5000 series and it seems to work fine for me.  the only thing i can suggest is to check your mouse settings in the control panel.  make sure that under the gestures tab, vertical scrolling is checked other than that i don't know what to tell you because as i said, it always worked for me.
