Firefox 2 RPM SPEC file & Recipe
Thomas Chung over at FedoraNews.org has a spiffy RPM Spec file he’s been updating for each release of firefox through 1.5.0.1. As it turns out the only change needed to update for version 2.0 is incrementing the version line in the file. Download the spec file and update line 2 from:
Version : 1.5.0.1
To Version : 2.0
You’ll also need the Desktop/Menuitem metadata file, the 
Firefox Icon and of course, the Firefox binary package from Mozilla.org.
Follow Thomas Chung’s detailed instructions and even the most novice Linux user should be able to build a Firefox RPM. I’ve been using this method for every firefox release since 1.0.7 to bridge the gap between the release and the date the Fedora project updates their RPM repositories. Recently though, as of 1.5+ I’ve found that the method above yields a more reliable Firefox installation that that offered in the Fedora RPM repositories - the latter displaying strange GUI behaviors and periodic odd crashes so I’ve moved away from the Fedora-provided Firefox RPMs entirely.
