1433504 - (ProxyBypass) Add a build flag for proxy bypass protection

Status: NEW

(Firefox Build System :: General, enhancement)

Description

[Arthur Edelstein [:arthur]]

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?

Comment 2

[Shane Caraveo (:mixedpuppy)]

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?

Comment 3

[Honza Bambas (:mayhemer)]

FWIW, Tor related bugs I've been involved in always have a pref to flip to enable respective features (off by default for Firefox).
