Best Firefox Add-ons for Capturing Full Webpage Screenshots

For a quick full-page screenshot, start with Firefox’s built-in Screenshot tool: open the page, choose Take Screenshot, then choose Save full page. You do not need an add-on for that. If you need batch capture, extra editing, or a particular export workflow, an extension may be a better fit.

This guide compares the native tools with three Firefox add-ons using their documented features. The sources reviewed do not provide a neutral head-to-head accuracy test, so there is no claim here that one extension captures every page best.

1. Firefox Screenshot: the simplest option

Firefox’s built-in tool can capture the full page, the visible area, a selected region, or an automatically highlighted page element. It can download the result as an image or copy it to the clipboard.

Open the page you want to save.
Right-click an empty area and choose Take Screenshot, or press Ctrl+Shift+S (Command+Shift+S on macOS).
Choose Save full page.
Download the image or copy it, depending on the controls Firefox displays.

If you use the feature often, you can add its button to the toolbar through Firefox’s Customize Toolbar screen. Mozilla says Firefox Screenshots collects interaction events such as use of the Copy or Save full page button, but does not collect the URL or details of the captured image. That statement concerns Firefox’s built-in feature, not third-party add-ons. Mozilla’s Firefox Screenshots guide has the current interface details.

2. Firefox Developer Tools: more control without an add-on

Developer Tools offer command-line and element-specific capture options. This route is useful when you need a particular node, a delay before capture, or a chosen device pixel ratio (DPR).

Enable the full-page screenshot button

Open Developer Tools.
Open Developer Tools settings and enable the Take a screenshot of the entire page toolbox button.
Use that button when you want a full-page capture.

Capture from the Web Console

Firefox’s Web Console provides a :screenshot helper. For example:

:screenshot --fullpage --filename full-page.png

To capture a selected element after inspecting it, use its CSS selector:

:screenshot --selector "main article" --filename article.png

For a page that needs time to settle, request a delay in milliseconds:

:screenshot --fullpage --delay 2000 --filename delayed.png

The documented options include --fullpage for content beyond the viewport, --selector for a node, --delay, --dpr, --clipboard, --file, and --filename. Consult Mozilla’s Web Console helper documentation for syntax and current behavior. The Inspector also offers a Screenshot Node command for capturing a selected node.

3. Firefox add-ons compared

Tool	Consider it when	Documented features	Things to check
GoFullPage	You want an extension-oriented capture and export flow.	The Firefox listing describes scrolling capture, PNG/JPEG/PDF export, configurable PDF page size, and a premium editor for cropping and annotation.	The listing says exceptionally large captures may split into multiple images. Check whether the free workflow includes the editing you need.
FireShot	You need batch capture or several export and sharing options.	The listing describes full-page, visible-area, and scrolling-selection capture; batch capture; and PDF, PNG, and JPEG output, with email, clipboard, and print options.	At research review, the listing showed a June 5, 2023 update and permissions including access to data for all websites, downloads, and messaging with programs outside Firefox. Recheck its current version, permissions, and privacy details before installing.
OpenCapture	You want a capture workflow with editing and redaction tools.	The publisher describes full-page and visible captures, crop, annotation, blur, and PNG/PDF export. Its repository lists an AGPL-3.0-or-later license.	The publisher says capture and editing are local and that tiled watermarking is the paid feature. Those are publisher statements, not an independent privacy audit; review the current listing and policy.

These descriptions reflect the respective Mozilla add-on listings and publishers, not independent performance tests. Store data, permissions, prices, and features can change. Review each add-on’s current listing before installing: GoFullPage on Firefox Add-ons, FireShot on Firefox Add-ons, and OpenCapture on Firefox Add-ons.

4. Choose by the task

One-off save or share: use Firefox Screenshot. It already handles full-page, visible-area, region, and element capture.
Selector, delay, or DPR control: try Developer Tools and the :screenshot helper before adding another extension.
PDF export or editing: compare the current GoFullPage and OpenCapture listings against the specific export or edit you need.
Batch capture: FireShot’s listing describes batch capture; verify current maintenance and permissions before relying on it.
Sensitive pages: inspect the add-on’s permissions and privacy policy. Treat local-processing language as a publisher claim unless independently audited.

5. Dynamic pages and capture edge cases

A full-page screenshot is not always a faithful record of everything a site can display. Lazy-loaded images may appear only after scrolling; content may continue updating; and nested scrollable panels may not be part of the document’s main page height. Different capture methods can handle these cases differently.

Lazy content: scroll through the page first if important images or sections have not loaded. Confirm the saved image includes them.
Nested scrolling area: a page-level full capture may include only the currently visible portion of an independently scrolling panel. Try capturing the element or panel itself.
Changing content: pause animations or wait for updates to finish; the Developer Tools delay option can help with a known wait time.
Very long documents: large captures can take longer and use more memory. GoFullPage’s listing notes that exceptionally large captures may be split into multiple images.
Page differs after capture: check whether content depends on login, consent choices, viewport size, or time-sensitive updates. A screenshot records what the browser rendered for that session.

6. Troubleshooting

Symptom	Likely cause	What to try
Take Screenshot is missing	The context menu was opened over a control, or the toolbar button is not present.	Right-click an empty page area, use the keyboard shortcut, or add the Screenshot button through Customize Toolbar.
The result stops at the viewport	A visible-area action was selected instead of full-page capture.	Choose Save full page in Screenshot, or use the Developer Tools full-page button or `--fullpage`.
A selector capture returns no useful image	The selector does not match the intended node or identifies a small/wrong element.	Inspect the element, confirm the selector in the page, and retry with a more specific selector.
Images or sections are absent	They load lazily or after an interaction.	Scroll the page first, trigger the required interaction, wait for the content, and capture again.
A panel is cut off	It has its own scroll container.	Capture the panel as a node if the tool supports it, or use the page’s own export function when available.
An add-on asks for broad site access	Its capture workflow may require access to page contents across sites.	Read the permission explanation and current privacy policy. Install only if the access matches your use case.

7. Cost, performance, and reliability

The built-in Firefox Screenshot and Developer Tools workflows avoid installing a screenshot add-on. Add-ons can save time when their particular editing, batch, or export features match your work, but assess any paid features and permissions from the current publisher or store page. No neutral benchmark in the reviewed sources establishes a fastest or most accurate option.

Large, dynamic pages naturally require more rendering and image memory than short pages. For repeatable captures, keep the page state and viewport consistent, wait for essential content, and verify the output. If the capture is important, retain the original page or use the site’s own export as a second source where practical.

8. ScreenshotNeo for repeatable API captures

If your goal is to capture pages from code or an automated workflow, ScreenshotNeo is a website screenshot API and MCP server from Yorker Media. It is an alternative to browser add-ons when you want a request-based capture, or an MCP tool for an AI agent. Its documented differentiators include removing cookie and consent banners, newsletter popups, and chat widgets before capture; billing only clean shots, with response headers identifying page verdict and billing; and MCP tools for screenshots, page info, and PDFs.

Or skip the browser setup:

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webp

import requests

r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);

Cookie banners, popups, and chat widgets are removed before the shot. Bot checks, blank pages, and failed loads are never billed. An MCP server lets AI agents take screenshots. The free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000. See the ScreenshotNeo API documentation for request options, and sign up for 1,000 free screenshots a month with no card.

9. FAQ

Can Firefox capture a full webpage without an extension?

Yes. Use Take Screenshot and choose Save full page. Developer Tools also supports full-page capture.

Which option should I install for PDF export?

GoFullPage and OpenCapture listings describe PDF export. Check their current listings for available formats and any plan limits before choosing.

Are add-on ratings a reliable way to choose?

Ratings do not establish capture accuracy. Compare documented features, permissions, maintenance information, and privacy statements for your needs.

Does a full-page capture include content inside every scrollable panel?

Not necessarily. A nested panel can scroll independently of the page. Try selecting that element or use a page-specific export.
