Too Bad they aren't offering the current version 1.4.1_03 which works great, however it needs to be manually installed.
Remember, for some, the Blackdown version might be required depending on what build of Mozilla you have...might check the Mozdev site to find out which one you need before installing anything. If built on the later GCC you will need Blackdown.
For Red Hat 9, the Mozilla 1.2.1 was built with GCC 2.95 and can use the Sun Version...works great!
