I cloned a sample project from the FF site and When I open the very same project on FF Windows app I get an error in the custom functions which then appears in the Web version of my project...
then when I click in the bug drop down content in the web project the error goes away. It only appears again when in the FF windows app. They should be usinb the same HTML engine right? Should be any difference using FF windows app or web? What is causing this problem?
