You can download the Firefox 3 – RC2 at the Mozilla web site if your feeling like you want to do a little testing.  If you have RC1 and you want to move to RC2, just go up to “Help” in the menu bar, then “Check for Updates”.

Check out the release notes for yourself and then download if your ready to take the leap.  Once again, must say this isn’t the final version just yet, so unless your just overly curious like some of us – might want to wait before downloading.
