Popup Blocker

About

Popup Blocker – Smart Per-Site Protection gives you precise control over how websites open new tabs, popups, and overlays.

Instead of blindly blocking everything, this extension works only on the websites you choose, making it powerful without breaking normal browsing.

Scripted popups (window.open)

Forced new tabs from links (target="_blank")

Programmatic click hijacking

Popunders and redirect tabs

Invisible click-through overlays (common on streaming sites)

Abusive “Are you sure you want to leave?” prompts

🎯 Smart & safe by design

Per-site activation (you choose where it runs)
