Scrolling In Firefox Is Horribly Slow

Is scrolling vertically on web pages in your Firefox horribly slow?

I encountered this issue recently on Fedora 10. Initially, I suspected the binary NVIDIA driver. But I was wrong. I found a simple solution.

Disable smooth scrolling in the Firefox preferences.

  • On the Firefox window click Edit
  • Click Preferences
  • Click Advanced tab
  • Click Use Smooth Scrolling to uncheck the checkbox
  • Click Close

Viola.
