Hey Bendower, I had this problem too when I upgraded from Win7 to Win8.1. Simple fix for me. '''results may vary''' Right-click the Firefox shortcut on your desktop, click ''Properties'', then click the ''Compatibility'' tab then click the checkbox that says ''Run this program in compatibility mode for:'' then select ''Windows 8'' from the drop down menu. Then click OK. Close existing Firefox browsers and reopen. It should work. If not, feel free to post back here.
