No Porn Please! di Liam Vu

Block all adult content ... in a unique way.
Trying to watch adult sites? No Porn Please! catches your "bad" intention and reminds you with a series of challenging popups. It's just really annoying at exactly the right moment.
Unlock 25+ challenging popups with math quiz, captcha, loading progress, and more!

Three things to help you quit:
- Popups that get in your way: A rotating cast of nonsense stands between you and adult content.
- Streaks that stick: Sign in and we'll count your clean days for you. Watch the number climb and get motivated!
- A loophole, sort of: Overcoming 4 popups will grant you some "free time." Your streak resets, though. Every action has a consequence.

How it works:
1. Install the extension
Add No Porn Please! from the Chrome Web Store, Firefox Add-ons, or Microsoft Edge Add-ons, and pin it up top where you'll actually see it.
2. Sign in & start your trial
Log in with Google to unlock the popups and get a 7-day free trial automatically.
3. Stay on track
Visit an adult site and the reminders show up uninvited. Close the tab (or don't — your choice!)
