Windows 10: Script error message now always opens during startup

A script error message started opening about a week after I upgraded from Win 8.1 to Win 10.
I hope to find what broke and why and whether I should fix it. Note: my chops are newbie level.

Here is the info in in the message. I guess it's about what broke in the script.

Question 1: I haven't a clue what this means. Can someone please tell me and whether it can be fixed?

It asks whether I want to keep running the script. Yes No. Since the message just told me the script was broken, I press No. The startup completes. I can't see that there are issues with how the computer operates.

Question 2: Is this serious enough to worry about? Of course, it is at least a nuisance. Worth fixing from that angle.

How to debug a script

I use Firefox in Windows 10. Every time I open the browser or Amazon website, I receive an error message: "A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script
continue."

The code: THREAD STUCK IN DEVICE

opened the debugger, but I do not know what to do with it, or how to find the line that I'm supposed to debug.

The message gives a link : http://windows.com/stopcode

 

WINDOWS SCRIPT HOST Error ''the Windows script host is unabled in this pc. contact your system customers''

Hi Johnson,

Which program is causing the error.. and what exactly is running at startup? Assuming no malware-laden script is running at startup: you can remove WSH restrictions using the registry editor. "Windows
Script Host access is disabled on this machine" Error (Fix)

To know which script is executed at startup, open Task Manager and click the Startup tab. Enable "Command line" column by right-clicking the column header. This shows the script file name that's configured to run at startup. Post back the information here.
You can copy the entry in Task Manager Startup tab by press CTRL + C.
