Actually, this is a powerful bookmarks replacement Rated 5 out of 5 stars

Oh my gosh! I didn't know that it's so powerful! After playing around with it, I discovered that it is much more than just a page with definable visual shortcuts. Actually, due to the possibility to create groups and have them in small subtabs (you need only one FF tab!), it's the fastest way ever to access your most needed bookmarks. You can even set a link to a group, thus navigating visually through your bookmarks. This is so intuitive and much easier than bookmarks toolbar or anything else. Setting up the whole thing needs some work though, in case you want everything very clean and visually perfect. But after you're done, it speeds up your browser experience a lot! Find thumbnails/logos for your Speed Dial links on userlogos.org or use Speed Dial's built-in function to create web page thumbnails, if you want the easy and fast set-up (but less nice-looking). Awesome! Thank you!
