hello bdesch, this sounds like a problem possibly caused by adware on your pc. #please go to the firefox ''menu ≡ > addons > extensions'' & remove ''MediaPlayer 3.1.0 '' which is malicious. #also go to the windows control panel / programs and remove all suspicious entries that got installed recently (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc) #finally, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner], which are specialised in adware and browser hijackers.
