Arrows and Pg Up/Dwn keys no longer function correctly in firefox.
When in a browser, if I use the down arrow keys to move down the page, the page immediately goes to the bottom, instead of the next section of screen to be displayed.
The Pageup/pagedown buttons have the same problem - they go to the absolute top and absolute bottom of the screen instead of going to just the next section of the page to be viewed.
I have tested it and I do not have this problem in IE which makes me think it is not a setting on my particular machine (ie: scroll lock, etc) but more something is off in Firefox.

Try hitting F7.
Sorry- didn't mention that I've already tried that. Also tried rebooting.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
