The website uses the ASP server-side programming language, which requires a Microsoft server, and the sourcecode of the website expects Internet Explorer (IE 11).
I tried enabling both javascript and external javascript handling, but the page load still won't get farther than the colorful background. Afterwards, I disabled external javascript handling, of course. There are other "features" of javascript that are still turned off by default: javascript.options.asyncstack;false javascript.options.discardSystemSource;false javascript.options.dump_stack_on_debuggee_would_run;false javascript.options.mem.log;false javascript.options.mem.notify;false javascript.options.shared_memory;false javascript.options.streams;false javascript.options.strict;false javascript.options.throw_on_asmjs_validation_failure;false javascript.options.throw_on_debuggee_would_run;false I found some clues to the problem here: https://www.makeuseof.com/answers/view-aspbased-website-android-phone/ But Abrowser doesn't appear to give any choice for user agents in the about:config page Mozilla has the right approach for this website's developer (Epic Systems Corp.) to adopt: https://developer.mozilla.org/en-US/docs/Web/HTTP/Browser_detection_using_the_user_agent George Langford
