Firefox is the last ever release for Mac OSX 10.3.9 and earlier versions. Which version of OSX do you have?

Firefox versions 3.0 and higher require OSX 10.4 and higher:

Firefox version is the last ever version of Firefox for OSX 10.3.9 and lower.

However, I would think about finding/creating an unofficial build of Firefox 3 for older Mac (if you cannot get next version of Mac OSX). If it's possible. I don't know.

Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store but may be available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).

Tiger Requirements... To use Mac OS X 10.4 Tiger, your Macintosh needs:

  • A PowerPC G3, G4, or G5 processor
  • Built-in FireWire
  • At least 256 MB of RAM (I recommend 1GB minimum)
  • DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
  • At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools
