I would like to have Firefox for my everyday use and the free download states that the current version is not compatible with this Mac Powerbook 4G OS 10.5.8. Is there an older version I could download at your website?

As of Firefox 4.0 and newer one needs both OSX 10.5+ and Intel hardware.

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

Since you have a PPC there is a third-party option for Firefox 9.0 at http://www.floodgap.com/software/tenfourfox/ however do note http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported if you use this build.
