Developer’s Description
Firefox command line interface. FFcli is a simple Firefox extension that adds a new dynamic toolbar to the browser, that is similar to the common find toolbar. Through this toolbar the user can execute predefined javascript functions. It is designed so that it can be brought up and controlled using only the keyboard, without time-wasting mouse clicks.
So the user can execute queries to Web pages like Google and wikipedia faster. The package already contains a set of shortcuts to some popular search engines and Web sites, but the user can add new shortcuts by editing the extension files. This version is the first release on CNET Download.com.
