How can I select the Quicktime plug-in (in Firefox) as the Helper Application, as only programs out of the web browser are shown?


I recently updated my QuickTime Plug-in (7.7.4) on Firefox 21. Prior to the update, I could open midi files in the Firefox and other browsers with a QuickTime Player. Now, I've got my Windows 7 computer asking how it should save or open the file. The QuickTime Plug-in is enabled and works with other types of files. If I open Tools, select Options, and select Applications, I do have the option of selecting "Use QuickTime Plug-in 7.7.4 (in Firefox)" for many file types. For the "Midi Sequence" type, it isn't an option, (only programs which open the midi files outside of the browser). Presently my only option is to use "Windows Media Player" as the default program, (opening midi files outside of the browser). "Mid file" allows the selection of the QuickTime Plug-in but still goes out of the Firefox browser to use the Windows Media Player, whether the file's extension is .mid or .midi

Is these someplace I can find the "Use QuickTime Plug-in 7.7.4 (in Firefox)" with the "Browse" within my computer's files, or am I now stuck using the "Windows Media Player" when a plug-in should be able to do this simple task? I can watch YouTUbe (in Firefox) but cannot play a midi file (in Firefox)!

If you start up QuickTime Player from the Windows Start menu (All Programs > QuickTime > QuickTime Player), you can try changing the "MIME" settings as follows:

Edit menu > Preferences > QuickTime Preferences > Browser tab > MIME Settings button

This will launch a Windows control panel where you can designate QuickTime to handler various kinds of media. You can group the MIDI entries together by clicking the Description column. (See screenshot)

I'm not sure whether Firefox will detect this change right away, or whether you have to restart it first. Does it work?

Question owner

Thanks for the suggestion, but I think that the problem is with the Quicktime Plug-in, (which simply is not shown as an option among the Applications available for the "Midi Sequence" (.midi files).

I have tried to amend the preferences and MIME settings in both QuickTime and thru the Control Panel for Default Programs and Set Associations. Plenty of file types have "Use QuickTime Plug-in 7.7.4 (in Firefox)" as a selection; and, if I could find it by browsing for that "application" (not selecting the "Firefox" program nor a driver file), there might be a ready solution. I prefer to be able to open midi files in another browser tab in Firefox or Internet Explorer, (rather than activate or use one of the programs (ie. Windows Media Player, QuickTime Player, etc.). As this problem is also encountered midi files opened with Internet Explorer, I suspect that the fault is with the plug-in in Apple's recent update.

The only other solution may be to restore my computer's settings and programs to an earlier time, then not to update the Quicktime.

QT 7.7.4 use "audio/mid" MIME type only and does not understand now "audio/midi" and "audio/x-midi" types commonly used on server side. Blame Apple for that.
