Tweaks to Speed Up Firefox

For a couple of days, I tried some tweaks for Firefox. To prove that they really work, I conducted a lot of speed tests at prior to and after the tweaks. It did not disappoint me. In fact, my page loading and browsing improved using Firefox.

Before we move on, I encourage you to make a system restore point or backup your preferences in Firefox so you can back track the changes or restore the original preference setting if you mess up.

To make a backup of Firefox preferences, just make a copy of the file prefs.js. This file is stored in your Firefox default directory.

Here's how to tweak Firefox:

1. Open your Firefox browser.

2. In the address bar, replace the web address with about:config as shown in the screenie.

3. Enter the following values by:
  • double clicking the preference if it is present by default;
  • right clicking anywhere in the browser then go to New then Integer or Boolean if the preference is not present by default;
(Do not include the comma)
browser.cache.disk.capacity, 15000
browser.cache.disk.enable, true
browser.cache.memory.capacity, 65536
browser.cache.memory.enable, true, true
browser.tabs.loadFolderAndReplace, false
browser.urlbar.hideGoButton, true
config.trim_on_minimize, true
content.interrupt.parsing, true
content.max.tokenizing.time, 2250000
content.notify.backoffcount, 5
content.notify.interval, 750000
content.notify.ontimer, true
content.switch.threshold, 750000
network.http.max-connections, 48
network.http.max-connections-per-server, 16
network.http.max-persistent-connections-per-proxy, 16
network.http.max-persistent-connections-per-server, 8
network.http.pipelining, true
network.http.pipelining.maxrequests, 8
network.http.proxy.pipelining, true
network.http.request.max-start-delay, 0
nglayout.initialpaint.delay, 0
plugin.expose_full_path, true
ui.scrollToClick, true
ui.submenuDelay, 0
4. Double check, then close Firefox.

Open the bowser again. Firefox must speed up now.
