PIIRUS Pop-up Blocker (browser add-on)
PIIRUS protects the PC. Our free browser add-on adds another layer against ads, trackers, forced pop-ups and scam websites — in Chrome, Edge and Firefox.
- Blocks forced pop-ups and pop-unders
- Blocks ads and trackers
- Stops known scam, phishing and malware sites, with a warning page
- Warns about look-alike and brand-new websites
- Auto-panic: clears fake virus and scare pages
- Optional: works with the PIIRUS app so blocked sites show in your alerts
The add-on is free and works on its own. Chrome installs from the Web Store; Firefox will ask you to confirm the PIIRUS add-on.
