    fixup! TB4: Tor Browser's Firefox preference overrides.
    
    In Mozilla Bug 1217290, a new WebGL mode was introduced specifically
    for `privacy.resistFingerprinting` set to `true`, which is supposed to
    give most machines the same WebGL profile.
    
    Previously, `webgl.min_capability_mode` was used for this purpose,
    but now that pref is intended strictly for browser testing and it
    overrides the `privacy.resistFingerprinting` setting. Furthermore,
    `webgl.min_capability_mode` can cause WebGL to fail unnecessarily.
    
    So we should not be enabling `webgl.min_capability_mode` any more in
    Tor Browser. This patch is the complement to a Torbutton patch which
    both remove that preference setting so it reverts to Firefox's default
    value (false).
