Monocle not working in latest versions of Chrome and Firefox

[YogiYang]

Hello,

I am trying out Monocle. But I observed that the books on the official web site: http://monocle.inventivelabs.com.au/

Are not working in Chrome (version 55.x) and Firefox (version 54.x)

What must be the problem?

I even tried this url of the book: http://monocle.inventivelabs.com.au/books/dubliners

But this also is not working.

Surprisingly this same thing is working in Internet Explorer (version 11.x)
