For "some" (I don't know why only "some") Mac users, detection of QuickTime plugin failed in latest Firefox 2.0.0.9. I use this code to detect QT plugin and get the version number with Firefox:

if(navigator.mimeTypes && navigator.mimeTypes["video/quicktime"] && navigator.mimeTypes["video/quicktime"].enabledPlugin)
{
    for (var i = 0; i < navigator.plugins.length; i++)
    {
        if(navigator.plugins[i].name.indexOf("QuickTime Plug-in")!=-1)
        {
            var words = navigator.plugins[i].name.split(" ");
            var version = words[2].split(".");
        }
    }
}

I have an iMac with MacOSX 10.4 / Firefox 2.0.0.9 / QT 7.3 , but I can't reproduce this problem. Anyway a lot of user report me the problem with different configurations. The example page always work with Safari in the same computer.

I found the problem. When navigator.plugins[i].name variable is read in Javascript code, Firefox 2.0.0.9 gives this text for QT plugin:

QuickTime-Plug-in 7.3

I saw this problem with English and German versions. But if I try the same code with Spanish version of Firefox 2.0.0.9 I get this plugin name for QT:

QuickTime Plug-in 7.3

Opera and Safari browsers return the correct name too, and I think old Firefox versions too:

QuickTime Plug-in 7.3

I think a lot of plugin detection scripts use "QuickTime Plug-in" name to detect the QT version, so it's important if Firefox returns the same string than the other browsers.

Thank you!

This bug was originally reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.8 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
