I have an extension for Firefox, "Close Repeated Tabs", and one for Chrome called "Tab Dupectomy"... but I really use Safari the most, and often have HUNDREDS of tabs open. I am desperate for a way to close, or ideally prevent from opening altogether - each tab that is for the SAME URL as another. I would imagine this is possible via an extension, script, etc.
