While there are a multitude of websites that you can access online using only your Internet browser, they are not all created equal. Some websites may not be coded correctly or may interact negatively with your Web browser settings. That can lead to problems, namely script errors. Script errors indicating that a script on the page is unresponsive can stop your Web surfing in its tracks and force you to stop necessary scripts on web pages. However, you can address unresponsive script errors by tweaking your browser settings.

Click "Default Level," then click "OK." Click on the tab marked "General" when finished.
