Details

(Whiteboard: [tor])

In Tor Browser, we have several patches that disable code that potentially could be bypassing the proxy. glandium suggested that, when we uplift these patches to Firefox, we should create a single build flag (let's call it --enable-proxy-bypass-protection) to control all of these changes. Here is a meta bug to track these these patches.

Would Bug 1376621 fit in here? Maybe we could use this build flag to omit the functions Tor was stripping out?

Build flags wont help in general (ie. Firefox official builds), we would need prefs to flip the behavior. Perhaps that could be added to this effort?
FWIW, Tor related bugs I've been involved in always have a pref to flip to enable respective features (off by default for Firefox).
