Zoom doesn't work in Firefox

[roback]

The problem is that the mousewheel event, used at

webgl-globe/js/globe.js

Line 178 in 3d4c802

container.addEventListener('mousewheel', onMouseWheel, false);

isn't supported in Firefox.

According to https://developer.mozilla.org/en-US/docs/Web/Events/mousewheel, wheel should be used instead (needs to be tested in other browsers to make sure it works there).
