How to speed Up Your mozilla Firefox

You all might be Thinking that firefox is already pretty damn fast then  can we really make it much faster? How is that possible? Can we really do it? These may be some of your questions when you see this post. But very few of us know that you can tweak firefox and improve its speed even more? Yah thats right, Firefox can be made much more faster than it is now.

I had to surf on for about 3 days to gather these much information. The most lovely thing that interested me about firefox is that its an open source program ,like all other open source programs which can be edited and can be made into more useful program, so is firefox.

Note : This tweak is not applicable for Firefox version 3.0 or above.

Here’s what you do:

In the URL bar of your firefox, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox. You must be really careful with the changes you make , cause any unnecessary changes you make can alter the functioning of your firefox.

Note that these are what I’ve found to REALLY speed up my Firefox significantly – and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections – I mean with as much concurrent requests we’re going to open up with pipe lining. you’d better have a big connection. 🙂

Double Click on the following settings and put in the numbers below – for the true / false booleans – they’ll change when you double click. These are some setting that you must change in order to obtain more faster browsing.


browser.tabs.showSingleWindowModePrefs – true (This setting wont be there for firefox version above 3.0 )
network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true
network.http.pipelining.maxrequests – 100
network.http.proxy.pipelining – true
network.http.request.timeout – 300 (This setting wont be there for firefox version above 3.0 )

Now Right-click somewhere on that screen and add a NEW -> Integer.  Name it “nglayout.initialpaint.delay” and set its value to “0”. This value is the amount of time the browser waits before it acts on information it receives. Since you’re broadband – it shouldn’t have to wait.

Now you may notice that your browser loads much faster than before.
