Block Coinhive from mining coins for others

Some days ago I noticed while I was browsing the web with Firefox Quantum 57.0.4 (64-bit) how the fans of my Macbook Air started running at full speed. Immediately I opened the Activity Monitor and I saw that the process responsible of this anormal CPU use was “Firefox Web Content”.

Afterwards I used Little Snitch to investigate who was responsible for it and I found out that a website was connecting to the domain coinhive.com to do JavaScript crypto coin mining.

The solution was simple, I added a new rule in Little Snitch to deny any outgoing connection to the domain coinhive.com

Now my Mac will not work mining to others via coinhive 😃
