Is a code audit the most efficient and reliable way to look for proxy
leaks? (At least at this stage?)  I think it would be useful and it's
good to be thorough, but it seems like it would be more efficient to
do a dynamic analysis for a first-pass effort, and to leave a code
audit to later in the game while you focus on some of the other tasks
you'll have.

I would do dynamic analysis by setting up a bridge and a proxy,
exercising lots of different functionality of the app (HTTP, HTTPS,
FTP, update checking, safebrowsing disabling/enabling, extension
installation, extension update checking, extension calls to third
party APIs, etc), and looking for any traffic not going to the single
bridge configured.

My 1 cent.
