Changelog

Last updated 5 September 2026

Every released version, newest first. A version number changes only when the extension does; the website is not versioned.

1.0.0

Awaiting review on addons.mozilla.org

First public release. These notes describe what the extension does rather than what changed, because nothing has shipped before it.

Six capture modes. "Full page including scrolling panels" returns one image containing the page and every inner scrolling column at full length. "All panels" returns a separate image per column. Those two are the reason this extension exists. The other four are single panel, full length scrolling page, selected region, and the visible window.

Sticky headers are settled before each tile, so a fixed header is captured once at the top instead of repeating down a long capture. This holds for headers that only become fixed after the page has been scrolled, which is the pattern most scrolling capture gets wrong.

Pixel rulers and draggable guides, with optional measurements between them. Guides can persist across a reload per page, and can be included in a capture for a redline.

Screen recording with auto-scroll. The viewport is recorded to a WebM file at its own resolution. Auto-scroll drives the page, or one panel you pick, advancing the same distance for every frame that is captured, so playback comes out evenly paced. Free records 10 seconds with a watermark; Pro records 2 minutes without one.

PNG and PDF export, clipboard copy, and a crop tool on the result page. Free still captures carry a thin credit line over the bottom edge; cropping above it removes it, and Pro captures have none.

Pro adds batch capture from a list of URLs, per-site presets, saved guide templates, capture diffing, text extraction from a selected region, and a searchable text layer inside exported PDFs.

A batch run saves PDFs by default.

Nothing leaves the machine. The extension makes no network requests of its own, declares zero data collection in the manifest, and keeps broad host access optional and requested only where a feature cannot work without it. Text extraction runs against an OCR engine packaged inside the extension, so no language data is downloaded and no image is uploaded.

Firefox 142 or later.
