1242121 - QuickTime plugin does not load on OS X 10.9.5 on FF 43.0.4

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[Alex Palecek]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20160105164030

Steps to reproduce:

Running Firefox 43.0.4 on OS X 10.9.5 Mavericks. Recently installed Apple's security updates 2016-001 and Safari 9.0.3. I'm not sure when the problem began, exactly-- up till a few weeks ago, things were fine. All of the software just mentioned was recently updated.

1. Attempted to listen to a .wav attachment in Gmail.
2. Attempted to view a QuickTime video on Apple's PR site. 


Actual results:

1. FF offers to open the .wav in an external audio application. 
2. Firefox fails to play the video.



Expected results:

1. Firefox should have played the .wav file in a new tab with a scrub bar, play button, and volume control.
2. Firefox should have played the video.

Troubleshooting steps: To test for trouble with the QuickTime plugin on my machine, I did 1 and 2 in Safari. Everything works as expected.

I also created a new Firefox profile as recommended here [https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles], to no avail. Same problem.

I dipped into Bugzilla here [https://bugzilla.mozilla.org/show_bug.cgi?id=688237] and here [https://bugzilla.mozilla.org/show_bug.cgi?id=780284] and followed the suggestions (run Safari first to 'preload' the plugin; delete pluginreg.dat filres and run Firefox in 32-bit mode once), but the trouble persists.

The QuickTime plugin is not listed in the plugins tab of about:addons.

No QuickTime in my Firefox! :(

Also, tested in Nightly on 22 Jan 2016, 21:04 PDT, QuickTime still broken.

Did you try to reinstall QT?

QuickTime on Mac doesn't appear to have a straightforward path to reinstallation.
