Windows 10: Firefox: VLC Media Player not listed as content type

I have 2 computers: Acer Veriton M4650G and HP Pavilion Notebook, each with Windows 10 Pro - exactly the same version/build on both: Version 1803 (OS Build 17134.407). Both computers have exactly the same version of Firefox: 63.0.3. Both have exactly the same version of the VLC Media Player: 3.0.4 Vetinari. Both computers have the VLC Media Player set to every possible default settings.

On the HP notebook computer, Firefox (Options>General>Applications) has the following Content Type: "MP4 Video File (VLC)" with the "Action" set to: "Use VLC media player (default)" (See attached image):



The Acer computer doesn't show a video Content Type: "MP4 Video File" or any video file option at all. I scoured the Firefox support forum and found this remark:

"A media player like VLC comes with its own drivers to handle all media types it supports. Firefox doesn't come with such drivers to handle all file types and for playing MP4 files Firefox checks the operating system to see whether it supports this specific file type.

On Windows this is usually done via Windows Media Foundation (Vista, Windows 7+). If there isn't support available on the OS then your only option is to open the files in a media player that supports this content type. Native in this context means support at the operating system level."

Since the issue seems to be at the operating system level that can mean that there is something in Windows that is responsible for this discrepancy.

Any assistance with this issue would be greatly appreciated.

New Windows Media Player Plugin for Firefox

Anyone who uses Windows Vista and Mozilla Firefox may be pleased to hear that the Windows Media Player team has now released a plugin for Firefox that should allow the browser to play WMP content on websites. Here are the steps to get it working:

• Installation of the Windows Media Player Firefox Plugin may require administrative access to your PC. It is recommended that you close all other open browser windows before continuing with the installation.
• Click the Install button to automatically download and install the Windows Media Player Firefox Plugin.
• Depending on your security settings, you may see a Security Warning dialog box. Click Install to install the plugin.

There is a known issue if you are using Firefox version 2.0.0.3 on Windows Vista with the installer failing with error code -203. To work around this simply restart Firefox (you will get a notification that Windows Vista will be changing the Firefox compatibility settings) and then install again - the second time should succeed.

The download is available here, and the new plugin works on all versions of Windows XP and Windows Vista (although it is mostly intended for Vista, as that currently has no WMP support in Firefox).
