Firefox 20 is no longer supported, no one should be using it.

This forum is for end user Firefox support, not for support for web developers. Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.
