Many years ago I used mod_pagespeed together with Apache as a "foward proxy" to significantly improve my mobile "web experience". I wanted to try it out this week but faced an issue - nowadays a big part of web is behind HTTPS. This is perfect, but completely breaks my use-case. I need the proxy to modify the traffic. I trust my own proxy, so how do I tell Firefox not to "CONNECT" to remote https servers and trust the proxy to do the TLS validation instead?
