How to Screenshot an Entire Webpage
Regular screenshots only capture what's visible on your screen. But what if you need the whole page — everything from the header to the footer, including content you'd have to scroll to see?
That's called a full page screenshot (or scrolling screenshot), and there are a few ways to do it in Firefox.
3 Ways to Screenshot an Entire Webpage
Method 1: FullScreenie Extension (One Click)
Install FullScreenie from Firefox Add-ons. Click the icon or press Alt+Shift+Z and your entire page is captured. You can then annotate it, save it, or share it with a link — all without leaving Firefox.
Method 2: Firefox's Built-in Screenshot Tool
Right-click the page and select "Take Screenshot", then choose "Save full page." This captures the page as a PNG but offers no editing, no format options, and no sharing.
Method 3: Developer Tools
Press F12 to open DevTools, then Ctrl+Shift+P and type "screenshot full." This is buried in menus and not practical for regular use.

When Would You Need a Full Page Screenshot?
- Filing a bug report — Show exactly what went wrong, in full context.
- Sharing a design — Show a client or teammate the complete layout.
- Saving a receipt — Order confirmations, invoices, booking details.
- Archiving a web page — Save it before it changes or gets taken down.
- Research — Capture reference material, articles, or data tables.
Tips for Better Full Page Screenshots
- Close popups first — Cookie banners and chat widgets will show up in your screenshot. Dismiss them before capturing.
- Wait for the page to fully load — Lazy-loaded images may appear blank if you capture too early.
- Use JPEG for smaller files — Full page screenshots can be large. Switch to JPEG in FullScreenie settings to reduce file size.
- Blur sensitive data — FullScreenie's blur tool lets you hide personal info before sharing.
Did you know? FullScreenie automatically stitches together multiple screen-height captures to create one seamless image — even on pages that are thousands of pixels tall.
