Power Close by Mosab Ibrahim

A firefox addon, for the tab addict, to close all tabs with urls containing a keyword or a domain name. For example, if you have many facebook tabs open and not in order, you can just use this addon, write "facebook.com", hit enter and voila, all facebook tabs are now closed!
