Full Page Screenshotter szerző: Amarjit

Full Page Screenshotter captures complete web pages in Firefox, including content below the visible screen.

Use Fast Capture for normal pages, or Dynamic Scroll Capture for long, lazy-loaded, app-style pages with vertical, horizontal, or nested scrolling.

The extension only captures a page when you click the toolbar button.
