Thank you for the reply. However the latest version of Firefox requires an Intel chip, my mac runs a powerPC chip.

Firefox 4 and later require a Mac with an Intel processor and OS X 10.6 (Firefox 16 runs on OS X 10.5). *http://www.mozilla.org/firefox/20.0/system-requirements/ For an unofficial Firefox 17.0.5 ESR compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at: *http://www.floodgap.com/software/tenfourfox/ *http://www.macupdate.com/app/mac/37761/tenfourfox *http://code.google.com/p/tenfourfox/wiki/ReleaseNotes1705 *http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported *http://code.google.com/p/tenfourfox/wiki/QuickTimeEnabler *http://code.google.com/p/tenfourfox/wiki/AAATheFAQ
