How to take a full-page screenshot in Firefox
In Firefox, the built-in screenshot tool can save a full page for a quick grab, while Captorify adds the rest of the workflow: scrolling capture, annotation, redaction, and local PNG, JPG, or PDF export.
Why full-page capture is tricky
A full-page screenshot is one image of an entire document, including the parts below the fold that you have to scroll to reach. That is harder than it sounds, because the browser can only show one viewport at a time, so a long article, pricing page, or chat transcript will not fit in a single normal screenshot.
Firefox does include a built-in screenshot tool that can save a full page, which is genuinely useful for a quick grab. What it does not do is edit, redact, extract text, or share with controlled links, which is where a dedicated extension like Captorify adds the rest of the workflow.
Install Captorify for Firefox
After installing, pin the toolbar button so it is easy to reach. Capturing and exporting are local and free, so you do not need an account to follow the steps below; you only sign in if you later want cloud features like durable redaction, OCR, or sharing.
Take the screenshot
With Captorify installed, capturing a full page takes a few seconds. You can do it entirely from the keyboard, or from the popup if you prefer to pick the mode visually.
What happens under the hood
Captorify first measures the full height of the page, then scrolls the tab in viewport-tall steps. At each step it captures the currently visible area using the browser visible-tab capture, producing a stack of tiles that together cover the whole document.
Those tiles are then stitched together into a single tall image, which is what you export. The pipeline is the same across browsers, with no Firefox-specific branch, so the captured result matches the Chrome build.
- Measure the full page height.
- Scroll in viewport-tall steps and capture each visible tile.
- Stitch the tiles into one image and save locally.
Export and edit
The stitched capture exports locally as PNG, JPG, or PDF, all produced in the browser without uploading the page. PNG and JPG are good for dropping an image into a ticket or document, while PDF is handy for long pages because it paginates the capture across pages.
If you need more than a raw image, this is where editing comes in: annotate the capture, redact sensitive details before it leaves your machine, or package it as a PDF for an external recipient.
- Export as PNG, JPG, or PDF, all generated locally.
- PDF paginates long captures for tickets and docs.
- Annotate or redact before sharing when needed.
Limits and long pages
Most pages capture cleanly, but extremely long pages have limits worth knowing. A capture is built from up to 100 tiles, and each output part is capped at 32000 device pixels, so a very tall page can be split into parts or truncated.
When a page exceeds the cap, Captorify shows a warning so you know the capture was split or cut rather than silently losing content. For pages past the limit, capture in sections and combine them.
- Up to 100 capture tiles per full-page capture.
- Each output part is capped at 32000 device pixels.
- Very long pages may be split or truncated with a warning.
