Can't submit a comment on a website because of disabled Javascript in Firefox Browser

I get an error message saying that Javascript is disabled in my browser and I need to write the code below the form with my comment in order to submit my comment to the website post. But I don't see the code to write down with my comment. This happens when I try to submit a comment at this website: https://authorbeckydvorak.com/prayer-requests/#.X0qkEPApCDY I am using Firefox Browser 79.0.5 (Build #2015758619). I have included the screenshot of the form to fill out for submitting the comment, the screenshot of the error message below as well the screenshot of the Firefox Browser version. How can I enable Javascript for Firefox Browser so I can submit my comment successfully without the Javascript error warning from coming up again at the above website which I have mentioned above? Please reply back soon. Thank you very much for your time and support.
