How do I reset the settings so I can play MPeg4 videos in the browser without a dialog box asking to download it? I've tried going under Settings but it won't let me select "Open in FireFox."

Could be about the media.play-stand-alone pref on the about:config page in case you modified it in the past.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

Its set at True. Is that the right setting or could it be something else?
