Demo presentation not working in Firefox

[yoisik]

Hi Rene, nice software you're developing! I tried to watch the demo in Firefox (latest version, Mac and iOS) but nothing happens. There's some kind of loading happening, but then I only see a black screen. I tried it in Chrome (Mac) and it works well. Maybe there's a needed plugin for Firefox?

Best!

PS: I'm a fan of Sublimeless_ZK :-), thanks for developing it!
