The videos are unusually choppy and pixelated no matter what the website is. They work perfectly fine on Internet Explorer however. Is there anything I can do to fix my firefox, or do I have to start using IE? (I really wouldn't want to) Things I have already tried: - Reinstalling Firefox - Reinstalling Flash player - Safe mode (videos don't work in that either) - Restarting my computer - Updating all plugins Additional info: Operating system: Windows Vista Firefox version: 3.6.3 == URL of affected sites == http:// == Firefox version == 3.6.3 == Operating system == Windows Vista == User Agent == Mozilla/5.0 (Windows; U; Windows NT 6.0; fi; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) == Plugins installed == *-getplusplusadobe16263 *Octoshape embedded video plugin *np-mswmp *Winamp Application Detector *Adobe PDF Plug-In For Firefox and Netscape *Default Plug-in *NPRuntime Script Plug-in Library for Java(TM) Deploy *The QuickTime Plugin allows you to view a wide variety of multimedia content in Web pages.
