Since Digg users seem to love posting builds of "Firefox 3.0" and there is the possibility that end users might download these releases thinking that they're the newest, greatest thing, the guys at Mozilla are going to rebrand Firefox 3.0 from "Deer Park" to "Minefield" 
I presume that when Firefox 3.0 gets branched it'll be renamed to it's actual codename.
Firefox 2.0 is going to keep the name "Bon Echo".
Minefield even has an icon!
I cannot open any page with my minefield I get an error about
XML parsing Error : idefined entity
Location : crome:\\browser\content\browser.xul
Line number 35, column1 :
window id = "main-window"
Help ! need my minefield!!!!!
