You can get the build here.  I've yet to install any of the Firefox 2 builds, which is totally unlike me.  I'm not usually happy unless I have at least 3 or 4 major alpha or beta applications on my desktop.  I'll take a peak at this one, but I'll probably continue to wait.  Why?

Two reasons:

1. Firefox 1.5 already does everything I want.
2. I'm addicted to my Firefox extensions and too many of them (as of the last time I checked) don't yet work with Firefox 2.  Don't take my extensions away from me!  I know that in many cases it's just a simple tweak to the install package, but I've got too many extensions to go through and do that for every one. (download, unzip, edit file, rezip, install)

Having said all that, Firefox 2 does look pretty cool, and I look forward to finally biting the bullet and downloading it soon.
