FullSnap Capture by AbdielApps sɣur AbdielApps

FullSnap Capture by AbdielApps captures entire webpages in Firefox by scrolling the active tab, stitching visible sections into one complete screenshot, and downloading the result as PNG or JPEG.

Use it when a normal screenshot only captures part of the page, such as long articles, documentation, dashboards, reports, receipts, or pages you want to save for reference. The add-on includes simple capture settings, including PNG or JPEG output, adjustable JPEG quality, optional timestamps in filenames, and an option that tries to reduce repeated sticky headers during full-page captures.

FullSnap Capture works on normal HTTP and HTTPS webpages. Browser internal pages, extension pages, add-on store pages, and some restricted sites cannot be captured because Firefox blocks extension access there. Very large pages may also hit browser canvas limits, and pages with videos, animations, sticky elements, or slow lazy-loaded content may not always stitch perfectly.
