You can tweak this 60 ms delay in code https://github.com/nolimits4web/Swiper/blob/master/src/js/mousewheel.js#L62 But note, if you'll tweak it good for personal you, then other users may have issues
Thanks for the response! I'm wondering if there has been any other talk about this situation? It happens on some of my co-workers machines as well.
Also, that didn't solve the slides advancing more than once.
I just noticed even the demo (http://www.idangero.us/swiper/demos/20-mousewheel-control.html) will skip slides in Firefox on a mac. This happens when using a Magic Mouse or the touch pad on a Macbook Pro.
Did you have try to play with 60 ms delay? Of course, i can tweak it to fix behavior in FF, but it will break behavior in all other browsers :)
I did mess with the delay where pointed me too, but I'm not sure I fully understand what's going on there. I had to take it all the way up to 700 ms in order for it to only advance a single slide in Firefox. This made it feel really sluggish/almost broken. I also saw that you were doing a check just above to get the proper mousewheel event, so I just wrapped that delay in a variable and changed the value based on the same check you were doing. This way it only affects the intended browsers. Thanks for your help.
