How to Get Rid of Script Error Popups
Scripts are used on many websites to provide user interactivity with embedded elements. In some cases, scripts on these sites will conflict with the script host on your computer. When this occurs, a pop-up will display on your screen informing you of the script-related error and ask your permission to continue allowing the script to run. Generally, these problems are server-sided and are not a result of a problem on your computer. You can, however, disable these notifications within the advanced browser settings.
Press the "Windows" and "R" keys simultaneously. This displays a "Run" box at the bottom of your screen.
Type "Inetcpl.cpl" in the "Run" box and press the "Enter" key. This opens an "Internet Explorer Properties" window.
Click the "Advanced" tab.
Click the "Restore Advanced Settings" button. This simply resets all of the options in the "Settings" section to their default values.
Scroll down to "Browsing" in the "Settings" section.
Remove the check mark in the box next to "Display a notification about every script error."
Click the "Apply" button to save your changes.
