Just wanted to add something: ..
The browser's name is Mozilla Fire
fox .. (the eMail application is called Mozilla Thunderbird). I also recommend using MZ Thunderbird instead of MS Outlook Express, because it is faster and way safer to use imo.
You can get Firefox at
http://www.mozilla.org/products/firefox/ :)
EDIT: ah, just came to realize that there is a Mozilla Browser called Firebird :D ... sorry, just didn't know it ;)
