Got the march 23 2018 version to work with Chrome, Opera and Edge, I can not get to work with the latest Firefox, PDF loading never stops and the control box is not centered. Any Clues? Thanks.
Did you test the official web site http://3dflipbook.net/ with firefox? Maybe you have integrated download manager into firefox that intercepts PDF?
I was using Jquery 3.3.1 flipbook use 3.1.1 looks like removing 3.3.1 solve the problem with firefox, all is well now,
