How to Take a Full Page Screenshot in Firefox
Need to capture an entire web page in Firefox — not just what's visible on screen? Whether it's a long article, a full design mockup, or a receipt you need to save, a full page screenshot grabs everything from top to bottom in one image.
Here's the fastest way to do it with FullScreenie, a free Firefox extension.
Step-by-Step: Full Page Screenshot in Firefox
Install FullScreenie
Head to Firefox Add-ons and click "Add to Firefox." It's free and takes about 3 seconds.
Go to the page you want to capture
Open any web page in Firefox. FullScreenie works on virtually any site — articles, dashboards, social media, you name it.
Click the camera icon
Click the FullScreenie icon in your toolbar. Or use the keyboard shortcut: Alt+Shift+Z
Choose "Full Page"
Make sure your capture mode is set to Full Page in settings. FullScreenie will automatically scroll and stitch the entire page together.
Annotate, save, or share
Your screenshot opens in the built-in editor. Add arrows, text, highlights, or blur sensitive info. Then copy to clipboard, download as PNG/JPEG/PDF, or share with a link.
Pro tip: Use Alt+Shift+D to quickly toggle between full page and visible area capture without opening settings.
Why Use FullScreenie Over Built-in Firefox Screenshots?
Firefox does have a built-in screenshot tool, but it's limited:
- No annotation — Firefox's tool just captures. You need a separate app to draw, add text, or blur.
- No share links — You have to manually save and upload the file somewhere.
- No format options — Firefox only saves as PNG. FullScreenie lets you choose PNG, JPEG, or PDF.
- No custom area — FullScreenie lets you drag-select any region of the page with Alt+Shift+A.
Common Uses for Full Page Screenshots
- Bug reports — Show the full context of an issue, not just a cropped view.
- Documentation — Capture tutorials, dashboards, or reference pages.
- Saving receipts and invoices — Capture the entire order confirmation page.
- Design reviews — Screenshot a full mockup or landing page to share with your team.
- Archiving — Save pages before they change or go offline.
