I've developed a small facebook game several months ago, and back then, when I tested it on Chrome, Firefox and IE, it was working on all three fine. Now, for some reason, it gets stuck on firefox. All it has in the "intro sheet" is to SET WEB FONT and PRELOAD AUDIO FILES. Then it has to wait for 3 seconds, fade screen, wait for 1 more and to go the next layout. I've tried omitting everything from the "intro sheet" and left only WAIT 3 SECONDS, GO TO "MENU" and it still gets stuck on the intro sheet.
Here's the link to the game, it will work on chrome and get stuck on firefox. http://apps.facebook.com/484339361599491/?fb_source=search&ref=ts&fref=ts
P.S. If it gives out an SSL ERROR you have to disable secure browsing on facebook (from ACCOUNT SETTINGS>>>SECURITY>>>SECURE BROWSING DISABLED) since the website this game is hosted on does not have an SSL certificate.
Can anyone tell me the possible reason why this is happening? I didn't change anything in the game's algorithm since I've tested it on the browsers. Is there any update that might cause this or?... I don't know guys, I've tried everything I could think of and i'm out of options..
Thanks in advance.
