## Review summary

CryptoMining Blocker is appreciated for effectively blocking mining scripts and improving browser performance without heavy impact. However, users frequently complain about intrusive and persistent notifications, lack of visibility into what is blocked, and overblocking legitimate crypto sites or scripts, sometimes rendering websites unusable. The inability to whitelist sites or hide notifications is a common frustration. Overall, it works well but could be improved by adding logging, a whitelist feature, and less intrusive notifications.

### Pros

- Effectively blocks crypto-mining scripts, improving performance and reducing CPU usage.
- Lightweight and works well across various sites including media streaming platforms.
- Provides noticeable improvement in browser performance by stopping unwanted mining activities.
- Users find it useful and reliable for protecting against unauthorized mining.

### Cons

- Annoying persistent notifications about blocked mining activities, which cannot be disabled or hidden.
- Lack of transparency: users cannot easily see which sites or scripts are being blocked or get a log of blocked items.
- Overblocking issues: some official cryptocurrency sites or useful scripts are fully blocked, rendering parts of websites unusable.
- No option to whitelist sites, causing inconvenience when legitimate sites are blocked.
- The plugin blocks entire websites instead of just disabling mining scripts, impacting usability.
