Files are missing from a scan
Load more of the webpage first: scroll, open the relevant gallery, and allow lazy-loaded content to appear. Scan again, then reset display filters. A file with unknown size or dimensions can disappear when a numeric filter is active.
Check Settings > Downloads for excluded image formats, custom extensions, or the 1 × 1 pixel option. A site may keep files behind a login, temporary URL, or protected player; GrabAll can only list resources exposed to the browser during the scan.
Download or preview is blocked
Refresh the source page and scan again to replace expired links. Check the browser downloads list for a blocked or incomplete request. A host may reject direct downloads or require the same signed-in session that showed the page.
A preview may fail even if the link is visible, because the host blocks cross-site loading or the browser cannot render that format. Try the file individually to learn whether the issue affects one result or the whole selection.
A page cannot be scanned
Browser settings pages, extension pages, and some protected destinations do not allow injected scans. Navigate to an ordinary HTTP or HTTPS webpage and try Scan this page again.
For a Mass Scan, remove tabs that cannot be scanned from the selection. If a URL-list scan contributes no files, confirm that the supplied page URL is valid and accessible, then check the combined Scan Results entry.
