Firefox and "one" secure site - Newsmax

[Gibbs]

I have Windows 10 and the latest version of Firefox.
ONLY on Newsmax do I have issues with accessing it. All other sites, never an issue
If I go to the top address and "Clear cookies and site data for Newsmax, I can see it once again. For a little while.
Soon it will halt me from seeing the content, and I get this message:

Also wanted to note that when I got that message on my Firefox browser, regarding opening NEWSMAX website, I could open up another browser I have, either Waterfox (Mozilla based) or Pale Moon and could see Newsmax without any issues.

Still having issues. Constantly, during the day, having to clear the site data and cookies for the website, Newsmax, to show up.
I have no other issues with any other websites.
Firefox also did an update just a day ago.

Is this the proper place to have this question?
