Yes, firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more?

That's the beauty of this program being open source.
Here's what you do:
In the URL bar, type "about:config" and press enter. This will bring up the configuration "menu" where you can change the parameters of Firefox.

Double Click on the following settings and put in the numbers below - for the true / false booleans - they'll change when you double click.



One more thing... 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 should notice you're loading pages MUCH faster now!

thanks it really helps a lot, hahaha

Here's something for broadband people that will really speed Firefox up:

1.Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:

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

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:

Set "network.http.pipelining" to "true"

Set "network.http.proxy.pipelining" to "true"

Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select 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 recieves.

If you're using a broadband connection you'll load pages MUCH faster now!

Here's a few tweaks that will speed up the loading of FireFox either from being minimized or from a first start up. I tried them and they made a significant difference in the time it takes to load FireFox.

* Tweak 1

Step 1.Typing "about:config" (without quotes) into the Address Bar to create a new, Boolean value, Right-click any row, then click and select New>Boolean. Type or paste the following string into the dialog box that appears:

config.trim_on_minimize

Step 2. Click OK to close the dialog box. Change the value from "true" to "false" and restart Firefox.

* Tweak 2

Speeding up Firefox on Windows XP

You can do this by right-click the Start Menu item for Firefox, or any icon (shortcut) you use to start Firefox, and open the Properties dialog box.

Add a space plus /Prefetch:1 to the command line and click OK. The resulting line might look as follows depending on where you installed FireFox:

"C:\Program Files\Mozilla Firefox\firefox.exe" /Prefetch:1
