The Power User’s Guide to Firefox 3 is a nice, albeit shortish, list of tweaks and tips for the new Firefox 3 browser. Unfortunately the 200+ comments don’t contain any useful additions to the list, just a load of complaints about the Firefox launch. Maybe the guys will do this post again to encourage more valuable comments? Or you can comment here if you have any more really cool tweaks to share with the world. Most useful for me?
