QuickTime plugin not available for Firefox 9 on OS X?

I'm trying to watch an embedded video in QuickTime format, but there is no QuickTime plugin in Firefox 9.01 on Mac OS X Lion v10.7.2. It says:

Additional plugins are required to display all media on this page. Install missing plugin?

I choose Install Missing Plugin and it says:

No Suitable Plugins were found: Unknown plugin (video/quicktime).

Checking Software Update says everything is up to date on my computer, and QuickTime Player.app is installed in the applications directory. In Library/Internet Plugins there is a file called QuickTime Plugin.plugin.

In Firefox Add-Ons, under Plugins, there is no QuickTime plugin at all.

Here's a site that embeds a video/quicktime MIME type, if someone wants to test. – slhck – 2012-01-26T20:45:43.757

QuickTime should already come with your system. There's no separate plugin to install.

If you type about:plugins into the Firefox address bar, you should see that the QuickTime 7.6.6 plugin offers support for the video/quicktime MIME type.

If you don't have this, then something is probably broken with your QuickTime installation.

A solution I found was the following:

  • Quit Firefox
  • Move the QuickTime Plugin.plugin file from Library/Internet Plugins away (e.g. to the Desktop)
  • Open Firefox again, go to Tools » Add-ons » Plugins to check that it's not recognized anymore
  • Quit Firefox
  • Move the QuickTime Plugin.plugin file back to where it was
  • Open Firefox again

The solution of moving the quicktime plugin file worked, but only after I restarted my computer. – jsherk – 2012-02-11T22:09:50.173
