Hey check this out and it really does work.

So it modifies about:config settings through a gui and automatically? I saw this listed in a firefox tweaks blog entry just yesterday where it was a highly recommended extension, and one they said worked wonders.
The only reason I haven’t checked it out yet is because their link to it was dead, thanks for finding this.

Its not an extension. Fasterfox is an extension but it no longer works for Firefox 3.0. This is a stand alone program.
I did mean that, thanks for the clarification.
