This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.

Install straight from GitHub with WP-CLI:

No built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.

A lightweight, efficient WordPress plugin designed to prevent unauthorized third-party websites from framing your content. By implementing a reliable client-side Frame Buster (Framebreaker) mechanism alongside native security headers, this utility effectively mitigates Clickjacking and UI redress attacks.

🚀 Features

  • Lightweight Footprint: Zero impact on site performance or initial page load metrics.
  • Instant Prevention: Immediately forces the browser window to navigate to the top-level frame if an unauthorized embed attempt is detected.
