---------------------------------------------------------------------------------------------------------------------------------Ubiquity is a firefox only extention that allows a user to add a command panelto any web pageYou start it up by using a quick key and it brings up a control panel with command suggestions consisting of "user-centric mashups" that let you perform tasks using various web services. This all sounds very confusing, but if you watch the video below it will begin to make sense.
