I am not very familiar with the details of XUL prototype cache, but my understanding of bug 1286082[1] is that currently the XUL prototype cache is not actually working correctly (and possibly has been broken since bug 592943[2] landed as part of Firefox 7 in 2011). So, an even more careful investigation / comparison is warranted. The prototype cache might not currently be doing anything.
