A free, open source browser extension blocking coin miners on websites, protecting your computer from resource utilization without consent
No Coin is a popular browser extension available for Google Chrome, Mozilla Firefox, Opera and Microsoft Edge. It works by detecting and blocking websites that utilize browser-based cryptocurrency miners like CoinHive to mine cryptocurrency without your consent.
This malicious practice is known as cryptojacking and can significantly slow down systems and drive up energy costs. No Coin stops websites from hijacking a user's CPU resources to mine cryptocurrency and helps protect user privacy at the same time.
As an open source extension with over 500,000 users, No Coin is transparent in how it works and is updated frequently to block the latest cryptojacking domains and services. It runs quietly in the background with little impact on browsing performance.
No Coin is a simple yet powerful tool that gives users control over their resources and prevents websites from using systems in the background without permission. With cryptojacking attempts on the rise, No Coin offers an easy way to avoid slow, unresponsive browsing and increased electricity usage.
