How can you 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 checkbox labeled
“Disable script debugging”. Uncheck the
checkbox labeled “Display a notifi cation for
every script error”.
Note: Please do this if you are absolutely
sure that you don’t want the script error
notifi cation; though the error notifi cation
doesn’t affect the page loading and
execution, users who want to test or
de-bug a web page should have the
notifi cation turned on.
