I'm a fan of GrApple Yummy, too - it's very well done. I'm also one of those that still thinks a Home button is a handy thing in a browser, so I always enable this button in Safari, instead of disabling it in Firefox, as you suggested. I still find myself using both browsers and haven't exclusively settled on one over the other yet. Good post. Thanks.
