Comment on attachment 461208 [details] Patch Again I'm surprised that enabling this extension was necessary. The functionality has been folded into the core ES 3.0 API. Perhaps the issue is that the surrounding code in WebKit is calling in through the extension entry points, and because this is a WebGL-compatible context, all extensions must be enabled manually. Regardless, r+.
