When I visit random pages on the Internet, I can get anywhere between 1 and 10 monotonous prompts with the title "Error" from Windows saying:

 

"A Runtime Eror has occured. 

 Do you wish to Debug?

 Line: 96

 Error: Expected 'j' "

 

And I can then choose to "debug" or not to do so.  If I choose "No," that prompt goes away, and another one just like it but with a different "line" and "error" could pop up, or they could just stop. 

 

However, if I click "Yes," I get another prompt with the title "Just-In-Time Debugging" saying:

 

"An exception 'Runtime Error' has occured in Script. 

 However, no debuggers are registered that can debug this exception.  Unable to JIT debug.  " 

 

Why is this happening and what can I do to fix it?
