Okay, this seems odd, and I may be doing something wrong. I downloaded Java jre-1.0.5_02, and installed it, then linked (ln -s) to the javaplugin_oji.so (/usr/java/jre-1.5.0_02/plugin/i386/ns7-gcc29) in Firefox plugins (/usr/lib/firefox-1.0.4/plugins), and then Firefox won't start. I remove the link, and Firefox starts! I've done this many times before. Am I doing something wrong, or is this a bug with Firefox (it works on my FC3 box), FC4T3 or even Java? Sorry about my previous posts (if you've seen them). Hopefully this formats better on the test list.
