Created attachment 341594 [details] prefs.js that breaks firefox firefox-3.5-0.20.beta4.fc11.i586 xulrunner-1.9.1-0.20.beta4.fc11.i586 nspr-4.7.3-5.fc11.i586 1. Remove ~/.mozilla 2. Launch firefox once to create a profile directory 3. Exit firefox 4. Drop the attached prefs.js inside the profile dir 5. Launch firefox " The connection was reset The connection to the server was reset while the page was loading. * The site could be temporarily unavailable or too busy. Try again in a few moments. * If you are unable to load any pages, check your computer's network connection. * If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. " Note that I never made any manual changes to the prefs.js, and that the only extension I ever installed (and then removed) was the google notebook.
When removing this from prefs.js user_pref("network.proxy.socks", "localhost"); user_pref("network.proxy.socks_port", 9999); user_pref("network.proxy.type", 1); everything works as it should (well, at least I can connect to external website).
