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 testmy.net 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
browser.search.openintab, 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.
