NoMiner - Block Coin Miners is a lightweight Firefox addon designed to block cryptocurrency mining scripts from running in your browser. By preventing these scripts, it helps safeguard your computer's resources from being used for coin mining without your consent. Users can easily manage which URLs are blocked through the options page, allowing for customization based on personal preferences. A toolbar button provides a simple on/off toggle, with the icon color indicating the addon’s active state.

This addon operates by continuously monitoring web pages for known coin mining scripts and instantly halting their execution. This proactive approach not only enhances user privacy but also improves overall browsing performance by freeing up system resources. With the rise of digital currency mining, NoMiner serves as an essential tool for users who want to maintain control over their computer’s capabilities while browsing the web.
