Here are the steps I took to install IBM's Java plugin for Firefox on
my x86 Ubuntu machine as a replacement of Sun's plugin:

*) go to
   and click on "Linux® 1.3.1 and 1.4.2"

*) click on "Download" (right-hand-side of screen)

*) after the signup screen (free registration)
 select "IBM SDK for 32-bit xSeries (Intel compatible) Version  1.4.2 SR1"

*) Download:
  tgz format   IBMJava2-JRE-142.tgz  (38.5MB)

*) at a command line prompt,  "tar -xvzf IBMJava2-JRE-142.tgz"

*) "mv IBMJava2-142 /opt"

*  to create plugin link for Firefox 
 ln -s /opt/IBMJava2-142/jre/bin/

 (don't forget to remove Sun's plugin  in that
same firefox directory)

After a few tests, some fonts in some applets actually look better
using IBM's version than Sun's version.
