Firefox disable browser zoom but allow element zoom on pinch

Question

I\'ve got a site running aimed at touchscreens running Firefox (very specific I know, but it will hopefully help with a solution) On the page in question, I\'ve got a d3 map

Answer 1

You might be able to do this using the viewport metatag and Hammer.js

This will disable the default browser zoom.

You can then use Hammer.js to capture gesture events which you will then pass to your D3.js code to zoom your map
