User reviews

CryptoMining Blocker is praised for effectively blocking mining scripts, reducing CPU load, and being lightweight. Users commonly request features like logs and block counts for transparency. However, multiple reviews mention issues with annoying persistent notifications, lack of clear information on what is blocked, false positives blocking legitimate crypto sites, and the problem of blocking entire websites rather than only mining scripts, which affects website usability.
Pros
  • Effectively blocks mining scripts and reduces CPU usage.
  • Lightweight and works well on various sites.
  • Users appreciate having it installed by default on fresh browsers.
  • Provides immediate improvement in system performance.
  • Users desire features like blocking logs and block count indicators.
Cons
  • Lack of transparency about what and where mining scripts are blocked (no visible log or list).
  • Persistent floating notifications that are annoying and interfere with browser usage.
  • Blocks entire websites instead of just mining scripts, rendering sites unusable.
  • False positives blocking legitimate cryptocurrency-related sites without whitelist options.
