it spike my CPU ...suspicious , behavior similar to CPU miner

Doesn't work. Crashed my browser.

Suspicious high CPU usage, fans spinning at high rpm ... while everything is idle with no tab open.

Works, except by the extremely high resource usage, the CPU and RAM usage is ridiculous

This is impossible to adjust, it blocks and lets through as it pleases. I don't think it can work any worse.

Literally used an entire 8gbs on my pc to do, what I assume is, bitcoin mining or something.

Did not block redirects.
