Same here. I'm getting:

> Firefox can’t establish a connection to the server at wss://clickclickclick.click/socket.io/?EIO=3&transport=websocket&sid=... websocket.js:111

> The connection to wss://clickclickclick.click/socket.io/?EIO=3&transport=websocket&sid=... was interrupted while the page was loading.

Reading the comments, it sounds the site is supposed to log everything that I do? Perhaps Firefox is blocking it?
