Build ID: 20120601045813
Steps to reproduce:
Firefox 13.0 was automatically loaded and run. Firefox 13.0 nolonger plays background MP3 sounds or embedded WMV files. Media Player does not even show a pannel on the pages.
No background MP3 sound or WMV player display.
Pages with embeded background MP3 sounds should have started automatically but did not.
Pages with embedded WMV files should have downloadd and displayed a Media Player pannel.
Does this still reproduce for you when using a current version?
