The site is up for me. Since yesterday I saw your same error on many Discourse sites using Firefox 59.x.  
It’s still this error ["Cannot Load App".... in Firefox sometimes. Refresh fixes it](https://meta.discourse.org/t/cannot-load-app-in-firefox-sometimes-refresh-fixes-it/85258)

It should be fixed when Firefox version 60 is released during the first week of May.  
If you click on the Try Again button your site should load normally
