FireFox is an excellent browser but I am now unable to use the Numeric Key pad and at times the whole keyboard will not work until I reboot.

Where is it that I would change whatever settings to use the Numeric Key pad. 
The Key Pad works fine otherwise.

I assume the keymap has been remapped?

Excuse me By reboot I mean quit Firefox and restart Firefox.

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).

The problem persists in safe mode. I have reset the preferences. Not sure what to do now.

Any ideas?
