The Frog
What it does is pretty simple...if you paste a link that you copied from a page which
you are browsing with the fish, the frog reconstructs the original url and opens a
new browser-window with it. This is sometimes useful when eg downloads fail to work. Other than that, if you paste any other url or text the frog will just take you to
the fish with that.
