firefox showing wrong version

[Scott Ehrlich]

On my Ubuntu Gutsy system with a recent apt-get update/apt-get upgrade:

scott at scott-desktop:~$ which firefox
/usr/bin/firefox
scott at scott-desktop:~$ firefox --version
Mozilla Firefox 2.0.0.11, Copyright (c) 1998 - 2007 mozilla.org


>From within firefox:

Help > About Firefox

Firefox
version 2.0.0.8


What am I missing, or what's going on?   Why isn't the application itself 
showing 2.0.0.11?

Thanks.

Scott
