Hey, I don't know if this will be any help, but I just managed to get java sorta working on my firefox with some blind luck. In newbie talk (my only language right now) this is what i did.
I downloaded the firefox binary to /usr/java
I ran it in the console
then I went to the /usr/java/jre1.5.0_06/plugin/i386/ns7 directory and made a symbolic link to libjavaplugin_oji.so in the same folder, so that the file and it's link were sitting next to each other. (i used file manager, the GUI is my crutch)
I renamed the link so it was the same name as its source file. I right clicked on the symbolic link and selected 'copy'
I then ran a file/folder search for EVERY folder with the name mozilla, or firefox, or both, and checked them for a 'plugins' folder. if it had a plugins folder, I pasted the link into it. I found like 3 of them.
After I had spammed this link to every plugins folder inside a mozilla or firefox directory, I was able to plat the java game reflex 2 on www.missionred.com
(a great test of reflex, accuracy, and your browsers java compatibility)
Now I know some experienced member is going to come in here and probably berate me for such a crude solution, but it apparently works. Can I get any uh... professional opinion on my fix?
btw make sure you dont copy the library file, just use a symbolic link with the same name, because one of the readmes or something on some sait said not to, and i belive them, because i used ONLY the link, and it worx. BTW im using Debian Etch and got the non RPM java
