Disable media device fingerprinting

[RoxKilly]

Describe the issue

Since Firefox 39, it may be possible for Javascript to fingerprint hardware media devices (microphones, cameras, etc...) through the MediaDevices API - in particular MediaDevices.enumerateDevices()

This can be disabled by setting the user preference media.navigator.enabled = false (source: search for the preference on this page

Since uBlock Origin has a privacy section in its settings, I wondered whether you would be interested in adding this option.

Duplicate of #1647 and many other such requests: counter-fingerprinting is a huge undertaking, worthy of being its own extension. People will have to find another developer, I can't volunteer for even more stuff.

You can modify user.js against privacy leaks, then use ublock for specific page elements.
