You can always tell when a new way of navigating through pages becomes popular, because you end up with three or four extensions for Firefox that do the same thing. With that said, I have one more add-on for Firefox that tries to copy what Google Chrome does with its page you get on a new tab or browser window. New Tab JumpStart does a great job at bringing Chrome’s thumbnailed pages you have seen before. One nice feature that I haven’t seen others follow up on is the ability to permanently “pin” page so it never goes away. You can pickup New Tab JumpStart from the Mozilla Add-ons web site.
