It seems to work quite well. I've found one bug with the noaa.gov weather radar looper not recognizing the javascript plugin, but otherwise I have had zero other compatibility issues and zero crashes. It is of course "beta" and not as customizable as people who really USE firefox might demand, but it's a nearly seamless migration from MSIE and I expect it will become my primary browser even in its unfinished form. I simply haven't had any showstopper problems except for the javascript issue, and that might be a problem with the website and not chrome.
