Yes you can!I have been waiting for the excellent ColorZilla extension for Firefox to update for quite some time now and was bummed that even though Firefox 3 had gone final that it still hadn't been released. After some digging today I found out why. The ColorZilla extension was rev'ed and the FF3 compatible version is ColorZilla 2.0.Download it here:ColorZilla 2.0More from the developer:Alex

The latest release candidate has shipped. The URL for the download is the same as before: http://www.mozilla.com/en-US/firefox/all-rc.html More info: Firefox 3 (Release Candidate 2) Release Notes Mozilla Wiki - Releases/Firefox 3.0rc2
