Add-on should recognize telephone numbers in any web page, and make them into clickable links, so you can call a number from Firefox in just one simple click. Clickable numbers are easily recognized by small gloCOM icon which is shown right next to the number. Also, you can also select any number and dial it from context menu just as in previous version.
