Actually, there is a way to tweak your favorite web browser, Firefox for better performance.
By typing about:config in the address bar, Firefox gives you access to loads of editable settings.
A little Firefox Tweaks
NOTICE: Make sure you backup all of the Firefox folder and appdata. You can use MozBackup to backup and restore your Firefox profile.
These tweaks are a .cheap and dirty. way to speed up the browser, and enable a few nice features. However, the more experienced net user might want to go ahead to the advanced tweaks too.
a>Type "about:config" in the address bar (where you usually type a web address to) without the quotes.
This will bring you to the built in configurator, (example of what it looks like) where the tweaking can begin
b>In the filter bar start typing HTTP, this will take you to the first set of settings we will change.
c> Change: network.http.pipelining to true by double clicking
d> Change: network.http.pipelining.maxrequests to 8 by double clicking then entering the new value in the box
e> Change: network.http.proxy.pipelining to true by double clicking
f> Change: network.http.max-persistant-connections-per-proxy to 8
g> Change: network.http.max-persistant-connections-per-server to 8
h> Change: network.http.max-connections to 48
i> Right-Click anywhere in the configurator and add a new integer. The name of this must be nglayout.initialpaint.delay and a value of 0
j>Restart Firefox by closing all windows and tabs and then reopening Firefox for the changes to become effective.Special for FX 2.0 only :
Fx 2.0 only: With Firefox 2, set the browser.startup.page key to 3 to restore your browsing session - with form entries intact! - every time you start your browser or undo close tab after a wayward click.
P/s: By default, Firefox 2 automatically restores your session if your browser crashes - but this does it every time you restart your browser normally
