AMO Page Helper (Sample) Autor: Kèo Nhà Cái.

This extension adds two focused tools to your browsing: a quick link highlighter that outlines all links on the current page, and a title viewer that displays the page title in the popup. It is designed to be lightweight and privacy-respecting. Scripts are injected only on demand when you click the popup, and only into the active tab. There is no remote code, no inline scripts, and no data collection. You can customize the outline thickness from the Options page; settings sync with your Firefox profile so your preference carries across devices.

The extension follows AMO guidelines: it avoids unsafe DOM operations, uses local script files, and requests only the permissions it needs. For usability, it includes a browser-style UI and accessible status messaging in the popup. If a site disallows script injection (for example, built-in Firefox pages), the popup will let you know without failing silently.
