Scripy error

Increasingly, when I am on Facebook, a dialogue box comes up - referring to a script error.I have a yes/no option offered.No matter which I select, the dialogue box appears and the site freezes.Only way I can exit is to use Task Manager.I am using IE when this happens.
What causes this and is there anything I can run to prevent it!
