Speed up Firefox

Firefox Speed

Mozilla Firefox has been considered the fastest browser by internet users across the world. Yet, did you know that you could actually speed up firefox even more ? Firefox has set some speed limits so that slow connections will get a good browsing experience, but for users with a fast internet connection, the true potential of Firefox is locked down by default. Here is a simple trick to unlock your maximum potential of firefox.

Fact to know before customizing:

HTTP pipelining is a technique in which multiple HTTP requests are written out to a single socket without waiting for the corresponding responses. The pipelining of requests results in a dramatic improvement in page loading times, especially over high latency connections such as satellite Internet connections.

Allowing HTTP pipelining will allow fast internet connections to reach their maximum potential. For this, a minimum internet speed of 256 kb/sec is recommended. The faster your internet speed, the better will be the performance improvement of Firefox.

If you’re sure you want to allow HTTP pipelining to speed up firefox, then lets start:

Type about:config in your address bar to start customizing firefox

Find the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Set network.http.pipelining to TRUE
Set network.http.proxy.pipelining to TRUE
Set network.http.pipelining.maxrequests to about “30“.

This means your browser can make 30 requests at once. Don’t set it above 30 otherwise some sites may consider you as a spammer.

Splash your web pages faster
In firefox, web pages load quickly, but appear on screen after a certain time. If you have a fast processor with a high RAM and a good graphics memory, then you can let the web pages appear on screen instantly. This will speed your performance but may be frying your processor. If you want to apply this trick, you can by changing the following value:

nglayout.initialpaint.delay

Change this value to “0″ to wait zero milliseconds to wait for splash screen. Mozilla suggests the value to be 250 for average speed computers.

That’s all. Restart Firefox to observe the changes. For a internet speed of 256 kb/sec your Firefox speed will become about 150% and for fast internet connections it can go upto 700%.

Basically Firefox has it disabled by mistake so that users with slow internet connections will also get a good browsing experience. But for high speed internet users, this function can be enabled manually. This makes Firefox even more customizable.

If you are a blogger or developer, you must try this. This will allow many HTML and JavaScript files to load simultaneously, giving faster page load.

Make sure you make note of what you change. You can always undo these changes later.

Try it out and tell us your results…..

      Chrome has a different way of running on the overall.. If you ask me, Chrome is not a browser, rather it is a simple software.. Firefox will always provide the satisfaction you need.. Glad this could help you :)
