WARNING: This is an unofficial Firefox build and comes with no guarantee that it will work properly. It is built from the same code as the Firefox 1.0 release, and seems to be working fine for the majority of people testing it. That said, this is still an unofficial build, so caveat emptor. I am not responsible if this doesn’t work, screws with your profile, causes blood to pour from your computer’s speakers, renders you impotent, or anything else.
That said, they work for the vast majority of people using it. So give it a shot, and post in the comments if you’ve decided that you love or hate me.
January 16: I’ve started building optimized Firefox builds from the latest nightly code, so if you’re interested in the latest, greatest, and most probably buggy, check out the latest nightly builds. If you’re interested in the optimized G5 builds which are more stable, download the Firefox 1.0 build linked below.
For the past two weeks or so I have been running a totally kick-ass nightly build of the Mozilla Firefox web browser optimized for the Powerbook G4 processor. Because it was created specifically for my laptop’s CPU, it is noticeably faster than the normal nightly builds. If you use a Powerbook (or iBook G4), you should check it out.
(Edit: I wanted to clarify that Kai Rune is the person responsible for the G4 builds, not me - I’ve seen some misleading linkage on the internets which makes it sound like I built the wonderful G4 version. The G5 builds are 100% my fault, however.)
Now that I own an iMac G5 (which I plan to post more about soon), I figured it would be interesting to see if I could build a version of Mozilla Firefox for the G5 processor.
With help I managed to get a version to build successfully. All of the rampant nerdiness was worth it: Wow, does this build fly on my iMac. For those of you who run a machine with a G5 processor in it (and who use FireFox), give it a try and let me know what you think.

If you install this, let me know what you think (if it works, if it’s faster for you, etc.) by posting in the comments.
Update (July 20): I have created a special BeatnikPad Mozilla / Firefox feed for those of you who are interested in just Firefox and other Mozilla-related updates. See how much I care? 
For those of you who want the full BeatnikPad feed (which includes Firefox updates) you can use this feed instead. Enjoy!
