How to take a full-page screenshot in Firefox
Firefox can capture an entire webpage without an add-on. Right-click an empty part of the page, choose Take Screenshot, then Save full page. Inspect the preview, then choose Download to save a PNG.
Use Firefox’s built-in tool first
- Prepare the page
Scroll through delayed content and return to the top. Close menus or dialogs that should not be included.
- Open Take Screenshot
Right-click an empty part of the page and choose Take Screenshot. Use Firefox’s screenshot toolbar control if you have added it.
- Choose Save full page
Select Save full page instead of Save visible or a drawn selection.
- Review and save
Inspect the preview, then download the PNG or copy the image. Check the downloaded result before sending it.
Check whether the whole page was captured
On our fictional page, Firefox’s actual native Download saved a 1280 × 7915 PNG. The last content marker was present. Capturing without first scrolling left the delayed image blank; scrolling down, waiting for it to load and returning to the top made it appear in the next native capture.
The inner panel and embedded document remain clipped in both native outputs. Check their final numbered rows separately rather than assuming a full-page PNG includes hidden content.
Compare the native PNG before loading the delayed image
Optional Captorify capture workflow
The current development extension was tested through Firefox’s real menu and popup. Capture succeeded; the native Save As picker after Export was not completed. Its result image is capture proof, not a completed export.
- Install from Firefox Add-ons
Use the official Captorify listing and review the requested permissions.
- Choose a capture mode
Open the toolbar button and choose full page, visible area or region. The extension also defines Alt+Shift+P, Alt+Shift+V and Alt+Shift+R shortcuts; check Firefox shortcut assignments if they conflict.
- Keep the page in the foreground
Allow scrolling capture to finish, then review the result and any warning. Do not assume a long image is complete just because an export is available.
- Export locally
Choose PNG, JPG or PDF, select Export and complete the save dialog. Local capture is free without an account. Turn off Sync captures to cloud before capturing anything that must stay local.
Handle a missing image or clipped panel
Scroll delayed images into view before taking another screenshot. A panel with its own scrollbar may need expansion, separate section captures or an application export.
An embedded document can be taller than its frame. Open the original document if the site provides that control, then inspect it separately.
Choose a readable output
For one screenshot, PNG keeps the captured pixels. For a long handoff or printed review, divide the image across PDF pages. An image PDF does not automatically contain searchable text.
Use the website tools if you already have a screenshot and only need redaction, OCR or PDF conversion.
Know the limits before sharing
Browser screenshots cannot reveal content the website never rendered. Captorify can split very tall captures into parts or warn that some content was not captured. Review warnings and the final source row.
Neither a full-page command nor an extension replaces a privacy review. Check the file you will actually send.
