Hi, Please check if this happens in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode] after enabling only the WMP (Windows Media Player) plugin in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons''' > '''Plugins'''.

I checked the add-ons; still doesn't work. I'm using Firefox 10.0.2.

One of the cam sites lists some troubleshooting steps involving the system [http://webcamsupport.keywest.com/ here].

Those cams use the Windows Media plugin. Does that plugin work on the test pages? *http://kb.mozillazine.org/Testing_plugins *http://kb.mozillazine.org/Video_or_audio_does_not_play *http://kb.mozillazine.org/Issues_related_to_plugins
