Description

Support for two new WebGL extensions was added during the ESR60 development cycle. We should verify that both are disabled via webgl.disable-extensions = true (which Tor Browser sets by default). See:

They are. They are in the whole WebGLContext::IsExtensionSupported() part which is first doing

    if (mDisableExtensions)
        return false;

before proceeding even further to consider the respective extensions.
