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). --- browser/app/profile/000-tor-browser.js | 1 - 1 file changed, 1 deletion(-)
