Rated 3 out of 5 stars
At first I was really impressed! But then I realized that the most operations are slower than with keyboard: Ctrl+L and +C is much quicker than pressing the button to copy. I don't need "Up" and even if: I'm faster with either double clicking a part in the Urlbar deleting it pressing enter. I don't need to surf anonymously, I can do the site search via g keyword, and I don't need the tags... that leaves me with the tinyurl wich is real nice! And I was actually looking for something like that. But all that just for the tiny?
Nonetheless: I think this is a cool addon for mouse-addicts. I'd really really suggest to change the dialogs: The green, blue and the script-font are quite ugly!
Another Idea for more buttons: Ok there are already extensions: But arrows for forward and backward would be nice too: They could filter the last number in the URL and in-/de-crease it by one. So you could browse numbered pages or pictures.
