This looks like it may be caused by Mixed content blocking in Firefox. Try disabling mixed content blocking on that specific website to see if the issue goes away.

If that doesn't help, it's possible that Enhanced Tracking Protection in Firefox for desktop is blocking certain Disqus-related content. You can try turning off ETP on the website to see if the issue is fixed.

If none of that helps, the next step would be to try running Firefox in Safe Mode to ensure that you don't have any add-ons installed that are causing the problem.

Hope this helps.

In addition to the first solution, I also cleared the website data and cookies and it worked. Thank you so much

Glad you got it working again!
