Best Firefox Add-ons for Full-Page Website Screenshots
Firefox can capture a full page without an add-on. Here’s when to use its built-in tool, which extensions offer extra features, and how to capture pages with an API.
Firefox already has a built-in full-page screenshot tool, so you may not need an add-on. Open the page, choose Take Screenshot from its context menu—or press Ctrl+Shift+S ( Command+Shift+S on Mac)—then choose Save full page. Add an extension when you need particular export formats, editing or annotation tools, or a scrolling selection.
This guide compares what the relevant Mozilla Add-ons listings say. These are listing descriptions, not hands-on test results; they do not establish which extension works best on complex pages.
1. Start with Firefox’s built-in screenshot
For a straightforward image of a whole page, start with Firefox’s own feature. Mozilla documents capture of the full page, the visible area, or a selected region. You can also add the screenshot command to the toolbar. Mozilla’s screenshot instructions explain the available capture choices.
- Open the webpage you want to capture.
- Right-click the page and choose Take Screenshot, or use Ctrl+Shift+S on Windows and Linux, or Command+Shift+S on Mac.
- Choose Save full page to capture the whole page. Choose the visible-area or region option when you only need part of it.
If you need a full-page or element screenshot as part of browser debugging, Firefox DevTools offers a separate workflow. Its screenshot toolbox button must first be enabled in DevTools settings. See Mozilla’s DevTools documentation for toolbox settings and capture features.
2. Firefox add-ons to consider
The options below are candidates for specific capture or editing needs. Features, compatibility, permissions, and listing metadata can change, so check each live Mozilla Add-ons page before installing.
| Option | What its listing describes | Consider it when | Limitations to note |
|---|---|---|---|
| OpenScreenShot | Full-page, visible-area, and region capture; editing tools; PNG, JPEG, WebP, and PDF export; clipboard copy and local screenshot history. | You want several capture modes and a choice of image or PDF output with post-capture editing. | The listing says desktop Firefox 140 or later is required and browser-protected pages cannot be captured. It lists version 2.1.4, updated Sep 22, 2026. |
| Full Page Screenshot & Webpage to PDF | Automatic scrolling and stitching, PNG/JPG/PDF export, and local editing. | You need PDF export along with a built-in editor. | The listing says extensions cannot run on internal pages, addons.mozilla.org, or other extensions’ pages. It lists version 1.0.2, updated Aug 16, 2026. |
| FireShot | Full-page, visible-area, and scrolling-selection capture; editing, annotations, and PDF features. | You need scrolling selection or annotation features described in its listing. | The retrieved listing information did not include current version or update details. Check the live page for maintenance and permissions before choosing it. |
| NeatForge Screenshot — Full Page Capture | Local scroll-and-stitch capture with PNG/JPG output; the listing claims it requests no host permissions. | You want a simple capture extension and want to review its stated permission approach. | The retrieved listing information did not show a version or update date. |
Version and update dates above are Mozilla Add-ons listing metadata, not quality or reliability ratings. The research did not establish comparative success rates on long, dynamic, or unusual pages.
3. Choose based on the job
- Just need a full-page image? Try Firefox’s built-in Save full page option first.
- Need PDF or editing? Compare the export and editor features listed for OpenScreenShot, Full Page Screenshot & Webpage to PDF, and FireShot.
- Need to capture only a scrolling section? FireShot’s listing describes scrolling-selection capture; verify that its current feature set matches your page.
- Capturing a browser-protected page? Add-ons cannot capture every page. OpenScreenShot’s listing specifically names protected pages, and Firefox restricts extensions on browser-internal pages and certain other browser pages.
- Working in DevTools? Use its separate full-page or element capture workflow after enabling the screenshot toolbox button in settings.
4. Privacy and permissions
Review the current permissions and privacy policy before installing any extension that can read webpage content. A listing’s privacy statement is a developer disclosure, not an independent audit.
OpenScreenShot’s listing says it does not upload screenshots or collect usage telemetry. Full Page Screenshot & Webpage to PDF says processing happens locally and it makes no network requests. Treat these as claims made in the respective listings, and check that the current disclosures still say the same before relying on them.
5. Capture limits and troubleshooting
| Problem | Likely reason | What to try |
|---|---|---|
| The screenshot command is missing. | You may be looking for a toolbar command or using a different Firefox interface. | Try the page context menu or the keyboard shortcut. Mozilla documents adding the screenshot command to the toolbar. |
| An extension will not run on the current tab. | Firefox blocks extensions on browser-protected or internal pages, including some browser pages and extension pages. | Try a normal website tab. These restrictions cannot be fixed by changing the extension’s capture settings. |
| The captured page looks incomplete. | Content may load only after scrolling, appear after a delay, or change dynamically. | Allow the page to finish loading and try again. If the extension offers scrolling capture, use that mode; results can vary with the page. |
| You need a particular file type. | The browser tool or extension may not offer the format you need. | Check the current listing’s export formats before installation. The listings described here mention different combinations of PNG, JPG/JPEG, WebP, and PDF. |
| A capture fails on a very long page. | Long pages can require more browser memory and may contain complex or independently scrolling content. | Try capturing a region or a smaller section, or use a tool that explicitly offers scrolling selection. No source in this research establishes a universal fix or comparative success rate. |
6. When an API is a better fit
A browser add-on is convenient for occasional manual captures. If your application or workflow needs repeatable captures from code, an API can avoid setting up and maintaining browser automation. ScreenshotNeo is a website screenshot API and MCP server; its API accepts a URL and can return a PNG, JPEG, WebP, or PDF. See the ScreenshotNeo API documentation for request options.
Or skip the browser setup
Here is a one-request capture of a webpage. Replace YOUR_API_KEY with your ScreenshotNeo key.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpScreenshotNeo accepts cookie and consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each cleanup step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits cost nothing, and response headers report the page verdict and billing status. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents. The free plan includes 1,000 shots per month with no card; paid plans start at $5 for 3,000 shots.

7. FAQ
Which Firefox add-on can capture the entire web page?
Several listings describe full-page capture, including OpenScreenShot, Full Page Screenshot & Webpage to PDF, FireShot, and NeatForge Screenshot. Firefox also has built-in full-page capture, so start there if you do not need extra features.
Does Firefox need an add-on for full-page screenshots?
No. Firefox’s Take Screenshot feature includes a full-page option labeled Save full page.
Can an extension capture every tab?
No. Firefox restricts extension access to browser-protected pages, and individual listings may state additional compatibility requirements.
Are the privacy statements independently verified?
No independent audit is established by the listing descriptions summarized here. Review the current developer disclosures and extension permissions yourself.
