Overview

draggable black rectangle lets you instantly mask any on-page content with a solid black box—no fiddly blur tools or incognito tabs required. Click the toolbar icon or hit Ctrl+Shift+Y (Windows/Linux) / ⌘+Shift+Y (macOS) to place a resizable, draggable overlay exactly where you need it. Need multiple masks? Just hit the copy button to clone an existing box. When you’re done, click the ✖ button to remove it.

Designed for seamless screen sharing, this extension ensures your passwords, private notes, or sensitive data stay hidden—even as you navigate or reload pages. Masks persist across navigation so you can focus on your call or presentation without interruption. No setup or configuration—install, click, and share with confidence.
