How to Take a Full-Page Screenshot in Firefox?

There are two different tasks when people ask how to screenshot in Firefox: capture what is visible on the screen, or capture the entire webpage. Use the operating system screenshot tool for the visible browser window and a browser/page level method for a full webpage.

Capture what is visible in Firefox

Use your operating system shortcut for Firefox chrome, tabs and dialogs. Firefox also has its own webpage Screenshot feature for content inside the page.

Capture the full webpage

Open Firefox Screenshots, then choose the full page option when you need the entire webpage. Firefox can also capture a selected region or the visible portion of a page depending on the current interface. Save/download the result and inspect sticky headers or lazy loaded sections.

Why full page capture can look different from the browser window?

A browser full page screenshot captures webpage content, not necessarily every piece of browser chrome. Sticky headers, lazy loaded images, ads, infinite feeds and animations can also change while a long page is rendered. Inspect the final result before relying on it.

Screenshot a menu, permission dialog or browser chrome

Use the operating system’s screenshot tool when you need tabs, the address bar, browser menus, permission prompts or another application in the same image. A webpage only capture tool generally cannot photograph UI outside the webpage itself.

Where the image is saved?

Operating system screenshots follow the save rules of Windows, macOS, ChromeOS or Linux. Browser generated full page images are usually downloaded or saved through the browser workflow, so check Downloads if the browser does not ask for another location.

Privacy and protected content

Review tabs, account avatars, bookmarks, addresses and notification surfaces before sharing a browser screenshot. Protected media or secure pages can intentionally limit capture. Do not use screenshot tools to bypass access restrictions or licensed content controls.

Useful details

• Firefox full page capture is ideal for webpages but not for other desktop apps.
• Dynamic/infinite pages can change while the capture is being generated.
• Use the OS screenshot tool when you need Firefox menus, address bar or permission dialogs.
