SpeeedUP Firefox – Tweaks For Better Browsing Performance


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.

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 pipelining… lol… you’d better have a big connection.

1. Disable Animations:
Step 1: Type “about:config” in address bar and hit enter.
Step 2: In the Search bar, type “browser.tabs.animate” and press enter.
Step 3: Now, Double click on the it and make it “False”.

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

2. Speed up Page Loading : 
Step 1: Type “about:config” in address bar and hit enter.
Step 2: In Search Bar type these commands one by one and replace the value one by one.

NETWORK.HTTP.PIPELINING => TRUE
NETWORK.HTTP.PROXY.PIPELINING => TRUE
NETWORK.HTTP.PIPELINING.MAXREQUESTS => 8
CONTENT.NOTIFY.BACKOFFCOUNT => 5
PLUGIN.EXPOSE_FULL_PATH => TRUE
UI.SUBMENUDELAY => 0
NETWORK.DNS.DISABLEIPV6 => TRUE
JAVASCRIPT.OPTIONS.JIT.CHROME => TRUE
JAVASCRIPT.OPTIONS.JIT.CONTENT => TRUE
4. Disable Antivirus Scanning:
Step 1: Type “about:config” in address bar and hit enter.
Step 2: Type “browser.download.manager.scanWhenDone” in filter and hit enter.
Step 3: Set the value from “True” to “False” by double click on it.


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! Enjoy it.
