SnapFold by Mansour Gilasgar

SnapFold is a screenshot tool for webpages that go beyond a normal page capture. Firefox's built-in screenshot tool can't see content that is scrolled away inside the page — SnapFold unfolds it first, so the image contains what the page actually holds.

Capture:

• The visible part of the current tab
• A complete webpage, with iframes and inner scroll panels expanded first
• A selected page element, fully scrolled out
• Independently scrollable inner panels and scrollable content inside iframes

This is useful for dashboards, web apps, chat windows, tables, settings panels, embedded tools, and other pages where the content you need sits inside a scrollable section rather than the main page.

After the shot, you choose what happens: open a preview tab with Download and Copy buttons, download straight away, or copy straight to the clipboard. Settings let you pick the image format (PNG or JPEG with quality), a filename prefix, a download subfolder, and more — the settings page includes a full how-to-use guide.

Privacy: screenshots are processed locally in Firefox. SnapFold does not collect, transmit, sell, or share any data. No analytics, tracking, external servers, or third-party services.

Known limits: Firefox blocks extensions on its own pages (about:*, addons.mozilla.org, the PDF viewer). Fixed/sticky headers appear once at the top of full-page shots. Infinite feeds that recycle rows can leave gaps. Requires Firefox 96+.
