Firefox has a "jerky" response to scroll wheel and keyboard input

Keyboard and mouse wheel response in Firefox is "jerky".

In the case of keyboard response, sometimes I can type steadily and see characters appear, while other times several seconds may go by before I see the letters I type (for example, in filling out this form it happened three times to this point).

The same is true of the scroll wheel on my Microsoft Intellimouse Explorer 2.0 mouse.

At first I thought it was system-wide as I spend most of my computer time on my work computer, but I recently realized it's really only Firefox.

I'd rather not do a total reset of Firefox if I can avoid it, as I still have a user chrome folder and a small handful of manually set about:config settings in addition to a few add-ons... unless I have certain knowledge that that will fix the issue(s).

Have you disabled hardware acceleration?

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
