Review+Audit Firefox 16 and 17 for next FF ESR release

We're going to need to start shipping FF17-ESR 'qualify' releases likely starting in December. We will need to switch over to FF17-ESR from FF10-ESR in mid-February or early March.

Here's the schedule: https://www.mozilla.org/en-US/firefox/organizations/faq/

Here's the developer urls: https://developer.mozilla.org/en/Firefox_16_for_developers https://developer.mozilla.org/en/Firefox_17_for_developers

In addition, I want to review the all FF17-ESR network glue code for changes to the proxy and DNS behavior, especially with respect to new HTML5 features.
