FullPage Capture Autor: mosfor

Full-page, viewport, region, or scrolling selection screenshots — straight to clipboard or file. No tracking, no servers. Everything runs locally and its opensourced under MIT license in github.

FullPage Capture gives you 4 capture modes with zero bloat:
• Full Page (Alt+Shift+1) — auto-scrolls and stitches the entire page
• Visible Area (Alt+Shift+2) — captures exactly what's on screen
• Select Region (Alt+Shift+3) — draw a rectangle to capture any area
• Scrolling Selection (Alt+Shift+4) — select a region, then auto-scroll to capture content taller than the viewport

Output options: clipboard (default) or save as PNG file. Toggle in the popup.

Smart features:
- Detects scroll containers (dashboards, SPAs with inner scroll)
- Hides sticky/fixed headers after first frame to prevent duplication
- Performance optimized for large pages

Privacy: No data collection. No external requests. Everything stays on your machine.
All shortcuts are customizable via about:addons → gear → "Manage Extension Shortcuts".
Works on Firefox 140+ and Zen Browser.
