How to stop pop-ups of script error messages?

When you're surfing the web, there are times when some of the scripts don't run correctly and you encounter lots of script errors.You can turn off these useless script error messages from popping up by doing the following: Click on " Tools | Internet Options |
Advanced " Now click the check box labeled "Disable script debugging". Uncheck the check box labeled " Display a notification for every script error ".

Note: Please do this if you are absolutely sure that you don't want the script error notification; though the error notification doesn't affect the page loading and execution, users who want to test or de-bug a web page should have the notification turned on.
