Hi myliang!

I am Naoto and using your "x-spreadsheet", and love working with it! However, I am currently facing a small issue that I would love to fix. I cannot scroll my spreadsheet horizontally on my Macbook's Trackpad in Firefox. On Chrome and Safari, there is no problem with scrolling on my Trackpad. I also found that I could also not scroll your spreadsheet (e.g. "Sheet-test" tab) horizontally with my Trackpad in Firefox. ( https://myliang.github.io/x-spreadsheet/ )

Do you have any ideas how to fix this issue / why it would happen? It would be very appreciated if you could take a loot this issue when you would have time.

Greetings from Munich,
Naoto
