Started happening a few months ago, happens all the time. It is happening in Firefox. I am using a laptop mouse and keyboard, both are fine it is not a hardware issue. It appears to be a settings issue in Firefox. Please help this is really annoying

Are you scrolling using the mouse wheel, or one of the buttons on the scroll bar, or another technique?


In case this is a problem with autoscrolling, you can disable that on the Options page:

"3-bar" menu button (or Tools menu) > Options > Advanced

On the General mini-tab, uncheck the box for "Use autoscrolling"


I don't know of any add-ons related to scrolling, but to rule that out, could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?
