This is being done instead of the update to 1.7.3 since the update breaks
all dependent ports, and that many changes is not a good thing to do during
a freeze.
This update covers the following Mozilla bugs:
245066
226669
250862
255067
256316
257317
258005
Thanks to nectar for scraping all of these patches together.
