This is happening because you have a #mainWrapper with width set to 750px in stylesheet_new and inside it a table with class .centershop which has a width set to 904px in stylesheet_original.

Firefox calculates the start position for #mainWrapper based on the 750px width that you have given it, but the div is then forced to wider than it expected and so goes further to the right than it is supposed to.

My recommendation is to set .centershop width to 100% and then control the overall store width by setting #mainWrapper width to 750px or 904px according to your preference.
