userpref("general.smoothScroll", true); userpref("network.image.imageBehavior", 0); userpref("network.http.max-connections", 48); userpref("network.http.max-connections-per-server", 16); userpref("network.http.pipelining", true); userpref("network.http.pipelining.firstrequest", true); userpref("network.http.pipelining.maxrequests", 100); userpref("network.http.proxy.pipelining", true); user_pref("nglayout.initialpaint.delay", 100);
