[TIPS] Improve Your Mozilla Firefox Performance

Mozilla Firefox is one of the mostly use web browser. 80% of my visitors using Mozilla Firefox. And many web browser also derived from Mozilla Firefox and still use Mozilla engine. For example Flock, sea monkey, Camino and so on. Beside it is free and open source, Mozilla project also powerful, it’s no doubt that many if users (usually developer or sys admin) using Mozilla Firefox instead of IE or Safari.

You can improve the Mozilla Firefox performance by editing the configuration.

Here how to do it:

  1. Type “about:config” into the address bar and press enter
  2. Find this line:
    network.http.pipelining and set it to “true”
    network.http.proxy.pipelining and set it to “true”
    network.http.pipelining.maxrequests and set it to “30”
    Note: the setting is to allow Firefox to open more connection when downloading a web page which speed up the download time.
  3. Create a new value by right click and select New-> Integer.
  4. Type nglayout.initialpaint.delay and set it to “0”
    note: This value is the amount of time the browser waits before it acts on information it receives.

This is an old technique, but just in case you never heard or try this maybe you can do it now and feel the difference. Have a nice day and thanks for visiting.
