I tried installing the mozilla 0.8 rpm from penguinppc.com, using alien. It installed fine, and I can run mozilla from the command line, which creates a .mozilla subdirectory in my home directory and spawns four /usr/lib/mozilla/mozilla-bin processes, but no window is actually ever displayed on the screen.
The terminal window from which mozilla is launched displays: Registering plugin 0 for: "*","All types",".*" Registering plugin 0 for: "*","All types",".*" and no further messages... I'm running Debian testing (although not updated to most current) Any suggestions on what to try next?
