This is a blunt tool. Some sites uses context menu events in a benign way. A better alternative is to simply bypass context handlers with shift-rightclick when necessary.

This isn't really a performance improvement. If webgl is disabled it's due to troublesome drivers. Forcing it on can crash things.

Those are the defaults anyway on supported platforms

Hey I didn't know about shift-rightclick. For me, disabling dom.event.contextmenu.enabled gives me both menus at once, then I tap Alt to get rid of the browser's menu if I want to use the app's menu underneath it. But I won't have to do that anymore.

If only shift would override userselect: none; as well
