How to get touch input in WebGL on mobiles

I can run my application from phone browser, but it is not interactable at all. It goes on several phones on full version firefox and on android version of chrome (chrome messages webGL have no full support), but have no touch inputs. Also this site shows webGL is compable to mobiles. Can I somehow get the touch events to simulate it in the app? Probably, I'm able to do something with server or html file to fix that?
