Use at your own risk! Overly complex install instructions. Requires downloading & running external files. Could not use. Despite neither my antivirus nor an online file scanning site being able to detect anything malicious in the file, it actually erased part of a software tool I tried to use to delete remnants of the install software left behind! Actually, part of the install software deletes itself after seemingly failing to do anything. I honestly can't imagine a more frustrating or suspicious browser addon!
