Upgrading FireFox to 1.0.3

[mailing.list at srivastava.mailshell.com]

I have visited the FORUM and found a link to above subject but it is
not clear what the best way is to upgrade FireFox to 1.0.3.

I have recently installed UBUNTU 5.04 and am new to Linux. Any working
solution to this problem.

Thanx
