Firefox 2.0 Tweak Guide
I usually install FasterFox (not yet available for Firefox 2.0) on my box so that my copy of Firefox runs smoothly, but I know that some of you prefer to tweak it manually. So for all of you control freaks out there, tweakguides.com has published a very complete guide to help you control every possible aspect of Mozilla's newest browser.
This guide refers to the latest official version of Mozilla Firefox Version 2.0. The guide is designed specifically for those running Firefox on Windows XP, however most of the tweaks in this guide apply to Firefox on other platforms.
