Firefox won't install bc of "Unsupported Architecture" when I clearly meet the System Requirements?

I installed Firefox 4.0 and upon clicking on the mounted image, I dragged and dropped the program into my applications folder, then because of unsupported architecture the program wouldn't launch. However, I read the system requirements before installation and I meet all of the above. I have a PowerMac w/ a Dual 1.8Ghz PowerPC G5 based processor, 1GB DDR SDRAM, and a 320GB Hard Drive running Mac OSX 10.5.8. After which I had to delete the program and restore firefox 3.6.16 using Time Machine.

Firefox 4 doesn't run on a PowerPC Mac.
Firefox 4 requires at least OS X 10.5 and an Intel Mac.

For Mac OS X 10.4.11 or Mac OS X 10.5.8 you can look at:

Firefox 3.6.x can be found here:

I must have misread the system requirements then, because I could've sworn that they said a PowerPC G5 based processor was supported on Firefox 4.0. My mistake. Ultimately when my mac told me unsupported architecture, I should've listened. haha. Never second guess your Mac. They're always right!
