Pages with auto update features such as live scoreboards won't autoupdate when displayed in Firefox.
Pages with autoupdate features (e.g. live scoreboards) won't update when displayed in a Firefox tab. Firefox recently installed replacing IE as default browser, several add-ons installed (e.g. Flashblock, AdBlock Plus, CoolPreviews, Real Player Plugin, Shockwave Flash, US English Dictionary, Move Media Player, Adobe Acrobat Reader, WPF, Veetle TV, Silverlight) no other problems observed.

The plugin "npmnqmp 071800999999" looks like crap. Maybe that's what's causing the problem. Try uninstalling it.
Hmm. Have you tried selectively disabling some of your extensions (e.g. Adblock Plus, Flashblock) to see if they were interfering with the autoupdate?
If you start up Firefox in Safe mode, you should be able to start Firefox with all extensions disabled. If that works, then you could try some detective work with activating extensions to see which one is the culprit.
