PCLinuxOS - 4 Tweaks to Speed up Firefox3

Firefox3 is very feature-rich, secure and usable web browser. It is a testimony of the power of opensource software. But while going to please everybody and serve many functions it has become little heavy and seems sluggish, especially during startup and first connection. Fortunately, you can tweak its settings to make it blazingly fast.

Here are a few of them that will help speed up firefox3.

#1
Open about:config in firefox3, type network.http.pipelining in the filterbar, then double-click on this line and its value from false to true. Likewise search for network.http.proxy.pipelining, plugin.expose_full_path and network.dns.disableIPv6 and change their values to true.

#2
Search for network.http.pipelining.maxrequests in the filterbar of about:config page, double click on it and change the value anywhere from 10 to 20.

#3
Rightclick in the about:config page and select New followed by Integer. And in the new Integer value box type nglayout.initialpaint.delay and click ok. In the integer value box type 0 and click OK. Likewise create two Integers - one content.notify.backoffcount with value 5, and the other ui.submenuDelay with value 0. 1. Similarly, create a New Integer, name it Network.dnsCacheExpiration and give its value as 3600.

#4
The last tweak is about loosening one of the firefox3 security features for fast browsing, so be careful. Turn off these two security options under the Edit>>Preferences>>Security section of firefox:

Security -> Tell me if the site I’m visiting is a suspected Attack site
Security -> Tell me if the site I’m visiting is a suspected forgery

Close the preferences window, exit Firefox, and then delete urlclassifier3.sqlite file in .mozilla/firefox/*/, i.e, rm .mozilla/firefox/*/urlclassifier3.sqlite (checkout for *, in my case it is loela80g.default)
