What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Firefox has built-in ways to capture a full webpage, a single element, or just the visible viewport. For a full-page image, enable the screenshot button in Developer Tools or run :screenshot page.png --fullpage in the Web Console. Use the Inspector’s Screenshot Node command for one element.
Open Firefox Developer Tools
Open Tools > Web Developer > Web Developer Tools, or use Ctrl+Shift+I or F12 on Windows and Linux, or Cmd+Opt+I on macOS. Opened this way, Developer Tools target the active tab.

Capture a full webpage with the screenshot button
- Open Developer Tools, then open its settings.
- Under Available Toolbox Buttons, enable Take a screenshot of the entire page. This button is not enabled by default.
- Click the screenshot button that appears in the toolbox. Firefox saves the image in its Downloads directory.
Capture one element in the Inspector
- Open the Inspector and locate the element in its HTML pane.
- Right-click the target node and choose Screenshot Node.
Firefox captures the selected node and saves the image to Downloads. For an element identified by a CSS selector instead, use the Web Console helper.

:screenshot page.png --fullpageMozilla documents these options:
--fullpageincludes webpage content beyond the current window bounds.--selector "CSS selector"captures the element matched by a CSS selector.--filename name.pngsets the PNG filename.--delay secondswaits before taking the screenshot, which can help capture a menu or hover state.--dpr numbersets the device-pixel ratio. Values above 1 produce a more zoomed-in image; values below 1 produce a more zoomed-out image.--clipboardcopies the screenshot to the clipboard. Unless you also use--file, this prevents saving a file.--fileforces file writing when another option, such as--clipboard, is active.
For full-page captures, the helper appends -fullpage to the filename. Reusing a filename overwrites the previous image, so use a different name for each capture you want to keep.
Capture the visible viewport
Open Responsive Design Mode and click its camera button to capture the viewport. Firefox saves the screenshot to its default download location. If Screenshot to clipboard is enabled in Developer Tools settings, the capture is also copied to the system clipboard.

Choose a route by what you need
| Capture goal | Firefox route | Distinction |
|---|---|---|
| Whole page | Enable and click the Developer Tools screenshot button, or run :screenshot page.png --fullpage |
The button must be enabled first; the console helper supports filename and other options. |
| One element | Inspector context menu > Screenshot Node, or console --selector |
The Inspector is direct for a selected node; the console helper accepts a CSS selector. |
| Current viewport | Responsive Design Mode camera button | Captures the visible viewport. |
| Delayed, named, or clipboard capture | Web Console :screenshot |
Set delay, filename, clipboard output, or device-pixel ratio as needed. |

Troubleshooting
- The full-page screenshot button is missing: Open Developer Tools settings and enable Take a screenshot of the entire page under Available Toolbox Buttons.
- A repeated screenshot replaced an earlier one: The console helper overwrites a file when the same filename is reused. Choose a new filename for the next capture.
- The clipboard capture did not create a file:
--clipboardprevents file saving unless--fileis also present. - A delayed state was missed: Add
--delay secondsto give a menu or hover state time to appear before capture. - The result is framed too close or too far: Adjust
--dpr; values above 1 zoom in, while values below 1 zoom out.

These directions reflect Mozilla’s documented labels and shortcuts. Developer Tools labels, layouts, and shortcuts can vary with Firefox releases or user configuration, so if a named control is not where expected, check the current Developer Tools settings. The screenshot button, Inspector node command, Web Console helper, and Responsive Design Mode camera serve different capture needs; choose the route by whether you need the whole page, one element, or the visible viewport.
