Nova Block от Juan Muñoz

Nova Block is a privacy-focused browser extension that locally blocks advertising, tracking, malicious domains, and user-defined sites. It includes configurable categories, per-site exceptions, a real-time floating monitor, and optional experimental media analysis.
All filtering rules and preferences are processed inside the browser. Nova Block does not transmit browsing history, visited URLs, hostnames, email addresses, or personal content. Access to HTTP and HTTPS pages is optional and requested only when the floating monitor or media evaluation is enabled.
Features include:
- Advertising and tracking protection.
- Security, privacy, content, and productivity categories.
- Custom allowlists and blocklists.
- Temporary protection pause for individual sites.
- Real-time advertising, tracking, risk, and isolated-media indicators.
- Optional topological and temporal media evaluation.
- Import of TXT, hosts, JSON, CSV, and RSS domain lists.
- Spanish and English interfaces.
- Reproducible, reviewable builds without remote code or obfuscation.
Some advanced features are experimental and can be disabled independently from the settings dashboard.
