TamperMonkey Script: Block and Remove Event Listeners

This TamperMonkey script dynamically blocks and removes specific event listeners (e.g., blur, visibilitychange, focusout) added by websites to prevent unwanted behavior such as focus loss or visibility changes. It intercepts event listener registrations and removes blocked listeners immediately.

Features

• Blocks specific event listeners such as blur, visibilitychange, and focusout.
• Tracks and removes already registered event listeners on window, document, or other elements.
• Provides console logging to inform you when an event listener is blocked or removed.
