  • Latest version

    Version 0.4.1

    Released Sep 17, 2026 - 67.75 KB
    Works with firefox 109.0a1 and later
    Fixed: The preview image now loads on pages protected by HTTP Basic Auth.

    Previously, Open Graph Checker listed all the tags on auth-protected sites (like staging environments) but the preview thumbnail failed to load. The image is now read in the page's own context, so it displays using the site's credentials — with no new permissions required.
