I'm having a unusual problem where proxy settings from another defined connection have permanently "contaminated" the settings written into the prefs.js for the browser. No matter what settings I choose for my current connection it always writes in the proxy settings from a former connection (I deleted it). Normally I don't use a proxy so the connection I've defined has the proxy settings blank and not set to use a proxy. Regardless, these other proxy settings are written into the prefs.js, making it impossible to connect to any sites. I've tried installing privoxy and setting the proxy settings to 127.0.0.1:8118 as you would expect; it does nothing, the old proxy settings from the former connection are written into prefs.js. I've hand-edited prefs.js (without the browser running), and used about:config to manually blank the proxy settings. Using about:config works until I close the browser, whereupon those old proxy settings are written back in. Any clues where the proxy settings are coming from and how to get rid of this behavior? And yes, I did restore from a backup when upgrading to the latest version of the OS. Thanks- Larry
