About this extension
Reddit NSFW Blocker is a fast, privacy-focused browser extension designed to automatically block adult subreddits, 18+ posts, and explicit search results on Reddit.
  • Automatic Subreddit Blocking: Immediately blocks navigation to known NSFW or 18+ subreddits.
  • Strict Feed Filtering: Automatically hides 18+ post cards from your home feed, r/all, r/popular, and search results.
  • Custom Blocklist: Add your own custom subreddits to block directly from the extension popup interface.
  • 100% Private & Offline: Runs entirely within your browser. Zero telemetry, zero analytics, zero data collection.
  • Dark Mode Ready: Beautiful, modern UI with high-contrast warning overlays.
