If you have RealPlayer Browser Record Plugin extension, disable/remove the RealPlayer Browser Record Plugin extension in the RealPlayer Preferences (RP: Tools > Preferences > Download & Recording) . Restart Firefox and test.
See Noah_SUMO's illustrated answer in this thread if the above is not clear: https://support.mozilla.com/en-US/forum/1/557689?
The RealPlayer Browser Record Plugin extension adds some extra features like saving media files.
Be sure not to get confused with the RealPlayer plugin (Tools > Add-ons > Plugins) that plays media files.

See this: http://vistasupport.mvps.org/run_as_administrator.htm
