I'm no expert, but it looks like you have a virus hijacking your traffic. What's with the .xn--org urls? Or maybe it's just a super overzealous adblocker.
I'd like to report as of June 21st at 4pm CDT, the site now works beautifully in my Linux Mint/Firefox system. I've made no changes other than a Firefox update was automatically installed so whatever you did - THANKS!
I did try your Apollo17.org site and it works beautifully in the same Firefox browser. And if I run Google Chrome, your Apollo 11 site works perfectly. Just not in Firefox.
I am running similar extensions in both browsers and I did disable Ublock Origin in Firefox but that had no effect. Apollo17.org in Firefox works fine with Ublock Origin enabled and I also run Ublock Origin in Chrome.
I'm willing to help out with debugging if you like.
