Firefox won't play mp3s

Posted on 2011-10-05

I built a site that has a Quick Time player embedded in the HTML with object/embed tags and this worked fine for awhile.  I was able to play the mp3s that are on the site.  But something suddenly knocked out this ability. Now when the site loads, instead of the player controller showing up,  it presents a download arrow and when you click the arrow it says "no suitable plugin was found."

I've looked at the Firefox plugins by putting "about:plugins" into the address bar. Quick Time Plugin 7.6.9 shows up seven times but the "suffixes covered" never include mp3.

The page loads and runs fine with Safari.

Does anyone know what might be going on?

The page is at, if someone cares to look at it.

Thanks for any ideas.

    Go to Tools -> Options -> Applications to see what Firefox is supposed to use for MP3 files.  I believe Quicktime Plugin 7.6.9 is blocked by Firefox for security reasons.  Get the new version of Quicktime 7.7.

    Hi Dave,

    Tools -> Options -> Applications shows mp3 files as VLC media files and to use Quick Time 7.6.9 in Firefox.    But I notice in "XP Folder Options --> Files"  that MP3 is shown as a VLC Media Type that opens with Quick Time.  There was a warning there, though, that said it had been customized and did I want to revert to the default action, which was to open it with the VLC media player.  When I said yes, everything worked again.  That is, Firefox now automatically opens the Quick Time player and plays the mp3s.  Apparently Firefox knows what to do wiith the MP3s as long as they were "VLC Media files" but when something changed this in Folder Options to be "Quick Time" files  Firefox didn't know what to do with the files.   At least I'm relieved that this is a weirdness with my XP system and not something wrong with  the site.

    I gave you the points since you got me to fiddling around in the right area.

    The Firefox blocking you mentioned of QT 7.6.9 may be on later versions of FF.  I'm running 4.0.1 and they seem to be letting QT 7.6.9 run ok.   Still, it seems like a good idea to upgrade to QT 7.7.  

    Thanks for your help.
