I was disappointed that FireFox and IE would construct different data structure representations. For example, in the array that I am worked with, the data were in index 0 for IE and 1 for Firefox. I also had to use
target sub-element within an array element for Firefox to find the data I was looking for, while I don’t needed to use it for IE. As a result, I had to find an IE detection code to add special conditional processing code.
