Does anyone know how to get rid of this annoyance, it displays a stupid Ad e.g. "You have won an iPad, click here" when mousing over certain words onscreen (Computer, not Tablet).
By a process of eliminating various Add-Ons/Extensions in Firefox I finally found the culprit. (It can be different for different users, just disable Add-Ons/Extensions until you find the one that's the rogue!)
