How to Take a Full-Page Screenshot of a Scrolling Dashboard in Firefox

By Freedom251 Team · · 3 min read

In Firefox, open the dashboard, choose Take Screenshot from the page’s right-click menu (or press Ctrl+Shift+S on Windows/Linux or Command+Shift+S on macOS), then select Save full page. This captures the page beyond the visible window. A dashboard panel that scrolls independently is a special case: Firefox’s full-page option does not guarantee that it will include rows hidden inside that panel.

Capture the full page in Firefox

  1. Open the dashboard and wait for the content you need to appear.
  2. Right-click an empty area of the page and select Take Screenshot. Alternatively, use Ctrl+Shift+S on Windows/Linux or Command+Shift+S on macOS.
  3. In the screenshot interface, choose Save full page in the upper-right. Choose Save visible only to capture the current viewport.
  4. Select Download to save the image to Firefox’s default download location, or select Copy to paste it into another application.

For quicker access, add a Screenshot button from Menu → More Tools → Customize Toolbar. Mozilla’s documented filename example ends in .png and follows the pattern “Screenshot year-month-day at hour-minute-second Page title.png”; that example does not establish that every Firefox build or workflow offers no other format options.

When the dashboard has its own scrolling panel

A full-page screenshot captures the page beyond the browser window, but a dashboard may place a table or chart inside a nested panel with its own scrollbar. Mozilla’s documentation describes whole-page and element captures; it does not guarantee that page-level capture expands every independently scrolling panel to include its hidden rows.

  • If the panel is incomplete, try capturing that element with Firefox Developer Tools.
  • Check whether the dashboard itself offers an export for the table or report.
  • If you need a single image and no export is available, capture the panel in visible sections and combine them in an image editor. This is a manual workaround, not a Firefox-documented automatic stitching feature.

Use Developer Tools for a command or a specific element

Enable the full-page screenshot button

  1. Open Firefox Developer Tools.
  2. Open Developer Tools settings and locate Available Toolbox Buttons.
  3. Enable Take a screenshot of the entire page.
  4. Use the newly available screenshot button to capture the page. Firefox saves the capture to the browser’s Downloads directory.

The DevTools screenshot button is disabled by default. Mozilla Firefox Source Docs: Taking screenshots.

Run the full-page command

In the Web Console, run:

:screenshot --fullpage

The --fullpage option includes page portions outside the current window bounds. The screenshot helper also supports options for a delay, device-pixel ratio, filename, clipboard, and selecting one element. For an individual dashboard component, use the Inspector’s Screenshot Node context-menu action. Mozilla documents element capture, but does not state that it reveals all content hidden inside a nested scroll area.

Which Firefox route should you use?

Route Best for Trade-off
Page context menu or keyboard shortcut A quick whole-page or visible-area image Fastest starting point; may not capture hidden content inside a nested scrolling panel.
DevTools screenshot button A repeatable full-page capture or element targeting Requires opening DevTools and enabling the button first.
Web Console command Command-driven capture and supported screenshot options Requires using the Web Console; it does not remove the nested-panel limitation.

See the ScreenshotNeo documentation for API options. ScreenshotNeo removes supported cookie banners, newsletter popups, and chat widgets before capture; bot checks, blank pages, and failed loads are not billed. Its MCP server lets AI agents take screenshots, and the free plan includes 1,000 screenshots per month with no card required; paid plans start at $5 for 3,000. For a nested dashboard panel, verify that the capture target and page behavior meet your needs rather than assuming an API will expose content the page itself keeps hidden.

Frequently Asked Questions

Can I copy a full-page screenshot instead of downloading it?

Yes. In Firefox’s screenshot interface, choose Copy, then paste the capture into another application.

Does Firefox’s full-page capture include rows below a dashboard panel’s own scrollbar?

Not necessarily. Firefox documentation does not guarantee that page-level full-page capture expands nested scrolling panels.
