关于此扩展

This Firefox extension enhances the YouTube experience by adding a convenient "Deep Link do itube" button next to the video controls. The button serves two main functions:

Copy Video URL – Instantly copies the current video’s URL to the clipboard.
Open Deep Link – Opens a custom deep link (itube-download-link://) for external download handling.

🔹 Key Features:

✔ Seamless Integration – The button is placed within YouTube’s native UI for a smooth user experience.
✔ Persistent Button – Uses yt-navigate-finish, yt-page-data-updated, and MutationObserver to ensure the button is recreated after page transitions.
✔ Efficient Performance – Avoids unnecessary CPU usage by only modifying the DOM when needed.
✔ Minimal Design – Styled to match YouTube’s interface with a simple, clean look.
🔹 How It Works:

The extension listens for YouTube’s internal navigation events (yt-navigate-finish, yt-page-data-updated).
A MutationObserver watches for changes in the UI, ensuring the button reappears if removed.
Clicking the button copies the video URL and attempts to open a deep link.
