In Firefox, hide the navigation element in Developer Tools before capturing the whole page: select it in the Inspector and press H. Take the full-page screenshot, then press H again to restore it. If you do not need the header or surrounding page at all, capture just the content element instead.
Why a sticky bar can appear in an awkward position
A fixed element is generally positioned relative to the viewport, so it stays in place as the page scrolls. A sticky element begins in normal document flow and sticks after reaching a threshold, relative to its nearest scrolling ancestor. These behaviors can complicate capture workflows that scroll or stitch page regions, but full-page screenshot implementations differ; there is no universal rule that every browser repeats sticky navigation.
CSS positioning behavior is described in MDN’s position property reference. If a capture contains a repeated or misplaced bar, use a method that omits the element rather than assuming every screenshot tool handles it the same way.

- Open Developer Tools and select the navigation or header element in the Inspector. If it is hard to click on the page, locate it in the Inspector’s node hierarchy.
- Press H while the node is selected. This toggles the selected node’s visibility; Mozilla documents the shortcut in its Developer Tools tips.
- Capture the page. Use the screenshot toolbar button in Developer Tools or enter
:screenshot --fullpagein the Web Console. If the toolbar button is not visible, enable it in Developer Tools Settings under “Available Toolbox Buttons.” Firefox’s Taking screenshots documentation covers full-page and element captures. - Restore the header by selecting the node and pressing H again. If you lose track of the change, refresh the page. H is a toggle, so leaving the page without restoring it can leave the element hidden.
The console helper also supports --selector for capturing a selected element and its descendants, plus options including --delay, --dpr, --clipboard, --file and --filename. The documentation notes that saving another image with the same filename overwrites the earlier one.
Use Firefox’s screenshot interface for a quick capture
For a straightforward capture, right-click an empty area of the page and choose Take Screenshot, or use Ctrl+Shift+S on Windows or Linux, or Command+Shift+S on macOS. Choose Save full page in the screenshot interface. Firefox also offers visible-area, region and element selection, and lets you download the capture or copy it to the clipboard. See Mozilla Support’s Firefox screenshot instructions.

Try the interface first if the page captures cleanly. If the navigation appears where you do not want it, hide the node with the Inspector workflow above or capture only the content element.
Choose the capture that matches what you need
- Full page: Use it when you want one tall image and the navigation is acceptable or can be hidden before capture.
- Element capture: Use Firefox’s Screenshot Node or
:screenshot --selectorwhen the main content is identifiable and you do not need the navigation around it. - Visible area: Use it when a single viewport is enough and the rest of the document adds no useful context.
- Hide one node: Use the Inspector’s H toggle when you want the page’s full content but not a specific header for this capture.
Firefox documents both full-page and single-element screenshots. You do not need to assume that a third-party extension is required to solve this problem.

Common problems and fixes
- The header still appears: Confirm the selected Inspector node is the actual navigation element, not a child or a similar-looking container. Hide the correct node with H, then capture again.
- The page looks incomplete: Check whether you used full-page capture rather than visible-area capture. If the page uses content that loads as you scroll, inspect the result and try the capture again after the content has loaded.
- The wrong content is captured: Use Screenshot Node or the console’s
--selectoroption on the content element, rather than the navigation element. - The screenshot button is missing: In Developer Tools Settings, enable the screenshot button under “Available Toolbox Buttons,” or use
:screenshot --fullpagefrom the Web Console. - An earlier screenshot was replaced: Give the next capture a different filename; Firefox warns that saving under the same filename overwrites the existing image.
- The header remains hidden: Press H again with the node selected, or refresh the page to restore its normal state.
