Mozilla 1.7 Beta is out

Mozilla 1.7 Beta is out, with some minor improvements...

Although I'm now using Firefox, I'm especially interested in those improvements "under the hood", e.g.

Mozilla 1.7 size and performance have improved dramatically with this release. When compared to Mozilla 1.6, Mozilla 1.7 Beta is 7% faster at startup, is 8% faster at window open time, has 9% faster pageloading times, and is 5% smaller in binary size.
