SitesNuker από Filip Krasnomowiec

SitesNuker helps you take control of your daily screen time on addictive websites. Set per-site time limits (in minutes), and when your time is up, the site gets blocked automatically. You can extend in small increments if needed, but the hard cap keeps you honest.

Key features:
- Per-site daily limits – choose how many minutes you can spend on YouTube, Reddit, Twitter, and other sites each day.
- Hard blocking – uses Firefox's declarativeNetRequest API to block sites at the browser level, not just with an overlay.
- Nuclear mode – instantly block ALL tracked sites for a chosen duration (5 minutes to 5 hours) when you need to focus
- Usage statistics – track your daily averages, weekly trends, and per-site breakdowns to see your progress over time.
- Smart domain detection — automatically recognizes aliases (e.g. x.com → twitter.com, youtu.be → youtube.com).
- Preset sites – comes with YouTube, Facebook, Reddit, Instagram, TikTok, and Twitter pre-configured (fully customizable)
- Multilingual – available in English, Polish, German, Spanish, and Russian
