I think it's darkly humorous that I have to install browser plugins to stop sites from mining monero in my browser. It's like websites are those creepy spider things in the Matrix, except instead of sticking humans in pods to harvest their biochemical energy, they're just running up our home electricity bills by maxing our CPUs.
I recently saw that I do get frequent crashes on certain pages, it appears that somebody is putting empty ads that do SHAsum in the background with WebGL using vec4 and shaders!
