[Timeline]: Horizontal and Vertical scroll by mouse wheel issue in Mozilla Firefox

[gam0ny]

Hi,
Thank you for the great tool! It covers really great part of functionality.

I'm experiencing an issue with timeline scroll by mouse wheel in Mozilla Firefox browser only.
The scrolling is really slow. It's clearly visible in the sample by the link:

Could you please assist?
OS: Windows 8
FF: 58.0 (64-bit)

vis.js // New school wheel delta (wheel event) :

var diff = delta / 120 * (this.range.end - this.range.start) / 20;

might become as a kind of fix :

if (navigator.userAgent.indexOf("Firefox") >= 0) {
var diff = delta / 3 * (this.range.end - this.range.start) / 20;
}
else var diff = delta / 120 * (this.range.end - this.range.start) / 20;

?!

Hi! Thank you so much for the idea of the fix! It really helped. Any idea how the fix can be requested in order to be included into the nearest build?

Good it helps but I would not feel comfortable pushing this quick&dirt fix into pull request.
Mousewheel event is deprecated, moving to wheel is probably the right fix long term but much more work to achieve. /my2cents

Is there any update on this?

The issue has been fixed, but since there hasn't been a new release with it and we only use the timeline, we have now switched to @yotamberk's https://github.com/yotamberk/timeline-plus.
