Worse, I think they meant to say "It's only tested in Chromium based browsers, beware" and they should let you pass anyways. I tried opening https://codux-demo

Worse, I think they meant to say "It's only tested in Chromium based browsers, beware" and they should let you pass anyways. I tried opening https://codux-demos.com/blueprint-css-webapp/ https://codux-demos.com/blueprint-css-webapp/ in Firefox but changed my User-Agent to Chrome on Windows. Everything works fine as far as I can tell. But all the network requests are slow as hell (probably HN-hug? Confirmed to be slow with cURL as well, so not because of Firefox).
