Miner Blocker
Miner Blocker - Block Coin Miners
Auto-block crypto mining scripts on websites before they drain your CPU, battery, and power.
Miner Blocker stops known cryptocurrency mining scripts as pages load - so CoinHive-style pools and similar miners cannot quietly eat your CPU while you browse. Watch blocked-miner counts in real time, keep filter lists and settings on your device, and browse without the slowdowns of in-browser Bitcoin or Monero mining.
Single purpose: block crypto miners on websites. Filter lists and settings stay local. No remote code.
