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 that I'm trying to enable pinch zooming for, however any pinch gesture is causing Firefox to set the zoom for the whole page. Is there a way to prevent the page zooming and only allow the map to zoom?
It's not an issue if I have to modify Firefox config settings but I'd prefer to avoid it and rely entirely on javascript if possible.
Thank you in advance
You might be able to do this using the viewport metatag and Hammer.js
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
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
