Sorry, but this forum is for end user Firefox support not for web developer issues. Please see this - Where to go for developer support
Mozilla web development StackOverflow thread. https://stackoverflow.com/questions/tagged/firefox+or+firefox-os+or+html5-apps
Or you could try posting at the Web Development / Standards Evangelism forum over at the MozillaZine fora. The contributors over there are more knowledgeable about web page development issues with Firefox. http://forums.mozillazine.org/viewforum.php?f=25 You'll need to register and login to be able to post in that forum.
