View Link Source ( RMB Context Menu) от sickplanet

Ever wanted to inspect the source code of a webpage or file without actually navigating to the link first and without force downloading it ? View Link Source streamlines this process by adding a native-feeling shortcut directly to your browser.

How it works:
Simply right-click any valid link on a webpage. A new "View link source" option will appear in your context menu. Clicking it immediately opens a new tab displaying the raw HTML, Text, Json, etc. source code of the target URL, using Firefox's built-in view-source: protocol.

Key Features:

Smart Visibility: The menu option is context-aware. It only appears when you right-click on an actual HTTP or HTTPS link, keeping your standard right-click menu completely clutter-free everywhere else.

Fast & Lightweight: Built on modern Manifest V3 standards, it runs only when clicked and consumes zero background memory.

Completely Private: This extension requires only the basic permissions needed to create the menu item and open a new tab. It collects absolutely zero user data.
