How to Capture a Scrolling Web Page with Awesome Screenshot in Firefox

Capture a full-page screenshot in Firefox with Awesome Screenshot, choose an export format, and troubleshoot missing controls or compatibility issues.

To capture a scrolling web page in Firefox with Awesome Screenshot, open the page, click the Awesome Screenshot toolbar icon, then select Capture Entire Page. Review the capture and save it as PNG or JPG, or download it as a PDF. If the extension icon is not visible, look for it in Firefox’s extensions menu or pin it to the toolbar.

Capture the entire page in Firefox

  1. Open the web page you want to save in Firefox and wait for its content to load.
  2. Click the Awesome Screenshot extension icon near the address bar. If it is not on the toolbar, look in the browser’s extensions menu or pin the extension to the toolbar. Menu labels can differ between Firefox versions.
  3. Select Capture Entire Page. This is the Firefox-specific command in Awesome Screenshot’s instructions.
  4. Review the resulting capture. Crop or resize it, add annotations or highlights, or blur information you do not want visible.
  5. Save the result as PNG or JPG, or download it as a PDF.

For the publisher’s Firefox-specific steps, see Awesome Screenshot’s full-page capture guide. Its Chrome and Edge instructions use a different sequence, so do not substitute their Capture then Full Page flow for the Firefox command.

Choose the right capture area and format

Need Capture choice Useful for
Save everything from top to bottom Capture Entire Page Long articles, documentation, and pages that extend beyond the visible browser window
Save only a chosen region Selected-area capture A chart, a section, or a specific visual detail
Save only what is currently visible Visible-part capture A quick record of the current viewport

The Firefox add-on listing describes full-page, selected-area, and visible-part captures. Choose PNG or JPG when you need an image file; choose PDF when a document-style file is more convenient to share. The editor also lists crop, resize, annotations, text, highlighting, and blur.

Review privacy and permissions before capturing

The Firefox Add-ons listing says the extension requests access to website data, browser tabs, clipboard input, and downloads. Its privacy disclosure says basic account and service-use information may be collected, including registered email, browser type and version, and service pages visited. Screenshot and video content is private by default unless the account owner chooses to share it. Review the current Mozilla Add-ons listing if these permissions or disclosures matter to your workflow.

When full-page capture does not work

Symptom Likely cause What to try
The extension icon is missing The add-on is installed but not shown on the toolbar. Look in Firefox’s extensions menu and pin the icon if available.
Capture Entire Page is missing The active add-on version, browser compatibility, or current page context may differ. Check the extension’s Mozilla listing for updates and compatibility, then reopen the page and try again.
The capture stops at the visible area The wrong capture mode may have been selected. Use Firefox’s Capture Entire Page command rather than a visible-part or selected-area capture.
The capture is incomplete or looks wrong Some page content may not have finished loading before capture. Wait for the page to settle and retry. If the site loads content only as you scroll, confirm the missing area is present in the page before capturing.
The extension no longer works after a Firefox update The developer warns that Firefox’s faster upgrade cycle can sometimes make the extension incompatible with the latest version. Check the Mozilla Add-ons listing for an updated version or compatibility information.

The listing identifies version 4.3.7.21, last updated November 19, 2025; that is a listing detail, not a guarantee of compatibility with every later Firefox release.
