Changing webgl.min_capability_mode to false in about:config in Torbrowser 8.0.6 is not persistant
I want to enable webgl in the Tor Browser 8.0.6. In about:config, all settings are saved except webgl.min_capability_mode, which is always set to true. Whatever I do, this value is always set true. All other webgl.*-changes are persistent. I tried adding a new default profile with a custom user.js file, without any success. Is this intentional, or is it a bug?
