v 1.2 broken in Firefox?

[NoLooseEnds]

It works in Safari, but not in Firefox and Chrome. I use Traefik as a proxy, and I think that could be the reason, but this issue what not present in the previous version.

Firefox:

Safari, works, but gives this:

[Warning] [blocked] The page at https://flame.hostname.tld/ was not allowed to run insecure content from ws://flame.hostname.tld/socket. (main.6f693952.chunk.js, line 1)

This issue wasn't present in the previous version because websocket was broken back then and wasn't connecting at all.

After quick googling it seems that Firefox is blocking insecure websockets connections with ws:// protocol.

I'll investigate it and either fix it or scrap use of websockets for now.
