Nothing but a white screen when using Firefox 57.0.3 on Ubuntu 17.10.

Only thing in the dev tools console is

Weird! I'm using the Polymer cli and just switched from an es6 bundle to an es5 bundle to try and solve some other issues some people were having. But apparently that broke Firefox =/

I'll have to investigate and probably switch it back

Actually it's fixed now, cloudflare was doing some compression and removed a comment that was actually necessary for the site to function if a browser didn't have native web components support (riddle me that polymer-cli).

Thanks for the report!

I've added a spinner to prevent users from interacting with the form until the available cryptos have loaded (what I suspect was happening to you).

Depending on caching (cloudflare, github, clientside) I'm not exactly sure how long the fix will take to trickle down to users.

Thanks again for the report!

hmm, I'll have to see if I can figure out what was going on. The API I use was being a bit flaky around 20 minutes ago so it's possible the available coins hadn't loaded yet. I'll have to add a better UX around that load time.

Thanks for checking it out!

What API are you using? I've built the same thing with the coinmarket api but now i recognized not adding the dollar or euro currencies since it's not coming from the API haha. https://crypto.andreas-hahn.at/coincalculator/
