It looks like Firefox is doing a good service for crypto enthusiast around the world by blocking third party cookies and cryptominers by default:
It's not just for crypto enthusiasts, it's about everyone, cryptominers are just a type of in-browser malware, and it's not even something that targets crypto users specifically, in fact it's probably the opposite as this malware is most effective when it's deployed on high-traffic sites.
It absolutely boggles my mind that Chrome has something like 70% of market share.
Most people don't know and don't care about privacy, and Chrome usually offers slightly better performance, less bugs and a bit faster load speeds. And Google as a giant company spent a ton of money on marketing Chrome. Also Chrome comes pre-installed on Android devices, and mobile platforms have already flipped desktops.
