So, this is my first foray into the world of config files and such so bear with me if I'm doing something completely wrong. I'm trying to write a mozilla.cfg file which will force proxy autodetection. I've used lockPref("network.proxy.type", 4) but I keep getting an 'failed to read configuration file' error when launching ff8. When I take this line out (I have some other settings in there), it seems to work ok. What am I doing wrong here? Also, as an aside, are there any settings which I can add to this file which will suppress the prompt about firefox not being the default browser?
