**Ultra Popup Blocker (UPB)** is a lightweight, high-performance userscript designed to neutralize modern popup techniques, redirects, and overlay advertisements. Built with a state-of-the-art interception engine, it operates silently in the background, protecting your browsing experience without breaking legitimate websites.

✨ Key Highlights

A stunning, blur-backed interface that feels native to modern operating systems. It adapts intelligently to your device:

(The responsive interface adapting to user interaction)

The "Black Hole" Proxy: Uses a recursive FakeWindow proxy that absorbs detection attempts. It tricks anti-adblock scripts into thinking a popup opened successfully, preventing site breakage while keeping the popup blocked.
State-Caching Architecture: Domain status checks are now O(1) (instant). Zero lag, even on the heaviest web pages.
Strict Mode: New option to block ALL popups by default, providing maximum protection.
Input Shield: Protects settings UI from hostile websites that block keyboard events.

Trap: Intercepts window.open, target="_blank", and simulated mouse events (including middle-click).
Shield: Monitors beforeunload events to prevent sites from redirecting your current tab in retaliation for a blocked popup.
Filter: Distinguishes between malicious popups and legitimate user actions (like download links).
Configurable: Toggle notifications or enable Strict Mode directly from the settings.

You need a browser extension to run this script.

UPB works out of the box. When a popup is blocked, you are in control:

Action	Description
✅ Allow Once	Opens the blocked popup just this one time. Useful for login windows.
💙 Trust Site	Whitelists the domain. Popups will never be blocked here again.
❌ Block Site	Adds the domain to the Deny List. Future attempts will be blocked silently (with a subtle toast notification).
⚙️ Config	Opens the dashboard to manage your Allowed/Denied lists.

Pro Tip: On mobile devices, the inputs are optimized to prevent auto-correct and auto-capitalization, making domain entry frustration-free.

This project is an evolution of the original concept, rebuilt for the modern web.
