I am extremely disappointed that it does not work... I just wish someone could make a working version of this addon which is a must have for anyone. Please remove this addon from the mozilla addons official website, If the developer has no intention of continuing with the development of this addon.
NOTE: I WILL GIVE 5 STAR RATING AND CHANGE THIS REVIEW TO A GOOD ONE IF THE DEVELOPER MAKES THIS ADDON WORK
