Quicktime videos play sound but no video in Firefox 4

I can't view any Quicktime video files in Firefox 4. My Quicktime plugin is up-to-date. I tried in Safe Mode, too, and still didn't have any luck.

I was testing with trailers on Apple.com - I figure they've got them embedded right - and only heard sound and saw the player controls. No video.

Does it help if you run the Firefox program as a 32 bit application?

  1. Close Firefox
  2. Open the Applications folder in Finder
  3. Control-click the Firefox.app icon
  4. Select "Get Info"
  5. Check the box, "Open in 32-bit mode"
  6. Close the "Firefox Info" window
  7. Restart Firefox

Thanks for your response! This worked for me. But... what does that mean?

I'm a web developer and trying to put an embedded streaming video on a website, so I ran into this browser issue while doing some pre-launch testing. I'll need to be able to help other people troubleshoot if they run into the same problem I did. It'd be cool if I could at least sound smart about it when explaining why the video won't play. :)

Does the fact that it works in 32-bit mode mean it's an issue with Firefox, not the video itself? Or would it be the Quicktime plugin? Would I just have to recommend using a different browser?

I'm not having a sound issue, but lots of stops and starts instead. Quicktime is atrocious in Firefox 4, but when I test a QT site with Chrome, it works fine.

This needs to be fixed at the code level... not using a workaround like this. :-(
