JavaScript warnings are generated when code is executed that doesn't cause a run-time error, but is non-standard, poorly written, or prone to cause logic errors. This preference controls whether JavaScript warnings are logged to the JavaScript Console.

 

Possible values and their effects:

False: Show JavaScript errors only. (Default)
