<h3>Elementor Widget</h3>
<p>If you’re using <a href="https://elementor.com/" rel="nofollow ugc">Elementor</a>, the PDF.js Viewer Elementor widget is automatically available in the Page Builder.</p>
<h3>Admin Notice After Updates / Invalid Block</h3>
<p>When you update the plugin, editors may see an admin banner explaining that Gutenberg could show an “Attempt Block Recovery” prompt when editing older posts with PDFs. Clicking it updates the block format; it does not affect what visitors see. You can dismiss the banner, and it won’t reappear until a future release enables it again.</p>

PDF.js Viewer


I was impressed with the level of support provided with the recent issue where the plugin stopped displaying due to Mozilla’s PDFjs, and they started using mjs files.



Thank you for an excellent plugin.
