After reinstalling FF it seems very slow now. After trying to get Firefox to work with youtube for a year STILL no luck. Reading that Youtube needs H264 but I am not seeing that in the Firefox Applications. Why is this after reinstalling Firefox?

Are you really using Windows server 2003 ?

Microsoft only prvides media feature packs to Windows Vista, 7, 8, 10 but not WinXP and I guess server 2003.

You can see what you can support HTML5 player at say https://www.youtube.com/html5/ as all check marks should ideally be blue.

Not sure if this guide for WinXP will work for server 2003. http://www.msfn.org/board/topic/175591-enable-mp4-h264-aac-html5-video-in-firefox-on-windows-xp-without-flash/
