This duplicate's NoScript's blacklist mode. Check off the option in NoScript to allow scripts globally, and it will use a blacklist instead of a whitelist.
It's a little misleading of this product to boast its usefulness because it does something the other product doesn't do by *default*. I find it a lot easier to just change my existing extension into blacklist mode than to uninstall it and install YesScript, which lacks many features of NoScript.
