I just downloaded/installed Firefox today to test web design for a class. This is not an upgrade but a clean install of 32.0.2. I'm running Win7 32-bit (6.1SP1)

I can not see any video in Firefox, though the files' audio routinely plays just fine. I have tested with files generated by me, and test files from the following sites:

http://camendesign.com/code/video_for_everybody/test.html http://www.htmlandcssbook.com/code-samples/chapter-09/example.html

The player controls come up, a grey box for the video player area comes up with a play button in it, but when I push play, there is just blank/white space, and the audio. I have tested both with the VLC plugin (2.1.3.0) and without - it makes no difference. All videos play just fine for me using IE and Chrome.

Any suggestions on why I'm the only person I know who can't view these videos in FF?

被選擇的解決方法

You have a very old video card with very old drivers. It's so old in fact, that looks like Nvidia doesn't even have drivers available that are certified for your operating system.

Graphics failures are listed in your system details, so this would be the first thing to try:

  1. Click the ≡ Menu Button and choose Options.
  2. Click the Advanced icon.
  3. Click the General tab.
  4. Uncheck "Use hardware acceleration when available".
  5. Restart Firefox.

If that doesn't help, try this:

  1. Click the ≡ Menu Button and choose Add-ons.
  2. Click Plugins.
  3. Set every plug-in to "Never Activate".
  4. Click Extensions.
  5. Click the Disable button next to every extension.
  6. Restart Firefox.

hello, your system information shows a few errors regarding your graphics hardware and a user.js file in your profile that shouldn't be present unless you've created it manually.

please try to reset firefox. afterwards disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect) and see if this can address the issue...

Disabling hardware acceleration did the trick. Thank you, everyone!
