How To: Speed Up Firefox Using the About:Config Menu

Speed Up Firefox Using the About:Config Menu

Firefox's hidden advanced menu gives you several ways to tweak the way it works under the hood. Here are a set of settings to change to get it to browse faster than ever.

Step 1: Go to About:Config

Go to the URL bar (A.K.A awesome bar) and enter about:config. If you want to use a more "graphical interface" use a Firefox GUI config.

Step 2: Now Search and Change These Following Values:

  • browser.display.show_image_placeholders = false
  • browser.tabs.animate = false
  • network.prefetch-next = true
  • network.http.max-persistent-connections-per-server = 8
  • network.http.pipelining = true
  • ui.submenuDelay = 0
  • network.dns.disableIPv6 = true

Step 3: Now Right Click, Select New Then Select the Options Accordingly.

Create integer -> Name: nglayout.initialpaint.delay -> value: 0
Create integer -> Name: content.notify.backoffcount -> value: 5

Step 4: Disable Useless Extensions:

Goto tools -> Add-ons -> Extensions -> Disable all the extensions you don't use.

Step 5: Disable Useless Plugins:

Goto tools -> Add-ons -> Plugins -> Disable all the extensions you don't use. For example i disabled the following:

  1. Google Updates
  2. Itunes application Detector
  3. Java platform SE update 7
  4. Microsoft DRM
  5. Windows Media Player Plugin
  6. Windows Presentation Foundation

Be careful when disabling plugins as some functionality of the browser may be disabled. Cover image by: ~IQEye

Nice set of tips! One thing to note: if you have a particularly slow connection, you should probably set network.prefetch-next to false as loading the next page before you need to might slow down some of your other activity.
