Firefox only works for root

[DuckDodgers]

This was in the readme from the firefox 0.9.1 download.

Note: If you install in the default directory (which is
usually /usr/local/mozilla), or any other directory where
only the root user normally has write-access, you must
start Mozilla first as root before other users can start
the program. Doing so generates a set of files required
for later use by other users.
