Sharingan Screenshot troch Sviriel

This extension captures the full content of the current web page by scrolling through it automatically, taking viewport screenshots, and combining them into a multi-page PDF.

Features:
- Captures full-page content, including long scrolling pages
- Saves the result as a PDF file
- Splits very tall pages into multiple PDF pages to avoid Firefox canvas size limits
- Works locally in the browser without sending page data to external servers

Notes:
- The extension uses the active tab and page access permissions only to capture the page the user explicitly chooses.
- Sticky and fixed elements may be temporarily hidden during capture to avoid duplication between screenshot sections.
- Very long pages may take a few seconds to process because Firefox limits screenshot frequency.
