How to install Firefox 2 in Debian Etch

My "standard" v1.5 install of Firefox began crashing without warning - so I installed Firefox 2 in the following manner:

Get Firefox
http://www.mozilla.com/en-US/firefox/

Untar the file in /opt

Copy your plugins:
$ cd /usr/lib/firefox/plugins
$ sudo cp * /opt/firefox/plugins/

Rename your old Firefox
$ cd /usr/bin/
:/usr/bin$ sudo cp firefox oldfirefox
:/usr/bin$ sudo rm firefox

Link your copy in /opt
:/usr/bin$ sudo ln -s /opt/firefox/firefox .

Done!
