It is usually not the kernel, but libraries that determine if you can run a specific Firefox version. * http://www.mozilla.com/firefox/5.0/system-requirements/ * http://www.mozilla.com/firefox/4.0/system-requirements/ * http://www.mozilla.com/firefox/3.6/system-requirements/ * http://www.mozilla.com/firefox/3.5/system-requirements/ * http://www.mozilla.com/firefox/2.0/system-requirements/ *Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html *Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html *ftp://ftp.mozilla.org/pub/firefox/releases/latest-3.5 *ftp://ftp.mozilla.org/pub/firefox/releases/latest-3.0 *ftp://ftp.mozilla.org/pub/firefox/releases/latest-2.0 ---- Firefox doesn't come with an installer or as an RPM package. You can download the tar.bz2 archive and extract the files to a directory on your computer in your Home directory or a system directory like /usr/local as root.
