Answer 1

Upgrade both your versions of Firefox & jQuery version from 1.6.4 to a more recent version.

This was filed as a bug in Firefox in FF11 & Patched as a result:

Bug #707677: getPreventDefault(); deprecated

As after all, the error messages refer to lines of source code that are completely unrelated to your code.

you can create new css with media type print

<style media="print">
#goBack,#printRow {
   display:none;
}
</style>

used this code

Intended for printed documents (applies to docs viewed in print preview mode too).
