As of Firefox 4.0 and newer one needs both OSX 10.5+ and Intel hardware. You have a too old OSX 10.4.11. You may be able to update to OSX 10.5.8 which can then run Firefox 4.0 and newer including Firefox 9.0.1

Firefox 3.6.* from Mozilla is the last to work on OSX 10.4.x. http://www.mozilla.org/en-US/firefox/all-older.html (Firefox 3.6.25 was released recently).
