Cool Tricks to Speed up Net surfing in Firefox

Type about:config in the address bar of the firefox

>> These settings are common to all the configuration files regardless of connection or computer speed with some additions - plugin paths can be found here about:plugins and the bookmark menu delay is turned off.

user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining", true);
user_pref("content.notify.backoffcount", 5);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("ui.submenuDelay", 0);
user_pref("plugin.expose_full_path", true);

For Fast Computer Fast Connection:

user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 2250000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("content.switch.threshold", 750000);
user_pref("content.notify.ontimer", true);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("network.http.max-connections-per-server", 16);
user_pref("content.notify.interval", 750000);
user_pref("browser.cache.memory.capacity", 65536);

A couple settings to note - Firefox is allocated 4096 KB of memory by default and in this configuration we give it roughly 65MB as denoted by the last line. This can be changed according to what is used.

Fast Computer Slower Connection:
This configuration is more suited to people without ultra fast connections. We are not talking about dial up connections but slower DSL / Cable connections.

user_pref("content.max.tokenizing.time", 2250000);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-connections", 48);
user_pref("content.notify.interval", 750000);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);

Fast Computer Slow Connection:

user_pref("browser.xul.error_pages.enabled", true);
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.maxtextrun", 8191);
user_pref("content.notify.interval", 750000);
user_pref("content.switch.threshold", 750000);
user_pref("content.notify.ontimer", true);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("content.interrupt.parsing", true);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);

Slow Computer Fast Connection:

user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 1000000);
user_pref("nglayout.initialpaint.delay", 1000);
user_pref("content.notify.interval", 1000000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("content.maxtextrun", 4095);
user_pref("content.notify.backoffcount", 5);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("dom.disable_window_status_change", true);

One of the changes made for this particular configuration is the final line where the status bar is disabled for changing web pages to save processor time.

Slow Computer Slow Connection:

We have entered the doldrums of the dial-up user

user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 750);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("network.http.max-connections", 32);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("dom.disable_window_status_change", true);
