This extension integrates Mozilla's open-source PDFJS library to replace the default PDF viewer in Edge browser, enabling progressive fetching, parsing, and local rendering of PDFs without server involvement. It supports top-level display of remote and local files (with "Allow Local Access" enabled for FILE scheme URLs), providing smooth experience. For embedded PDFs in iframes, enable via right-click context menu ("Support embedded PDFs"). Features: 1. Light and dark theme options, with OS theme support and custom CSS for appearance customization. 2. Page navigation via "page" hash, thumbnails, bookmarks/outlines, and keyboard shortcuts (next/prev, jump to page). 3. Full-text search with highlighting, text selection/copy, and document properties view (title, author, etc.). 4. Drag-and-drop opening of PDFs, plus download/print support via browser dialog. 5. Displays signed/unsigned PDF signatures (no verification). 6. Partial support for PDF scripts and rendering interactive forms (AcroForm/XFA; can disable). 7. Editing tools: Insert text/images, draw/sign with pen/mouse. 8. Crop/extract pages to create new PDFs. 9. Pause extension to revert to native viewer temporarily. Available Rendering Options: - Disable Page Labels - Enable Permissions - Enable Print Auto-Rotate - Enable WebGL - History Update URL - Ignore Destination Zoom - PDF Bug Enabled - Render Interactive Forms (AcroForm/XFA) - Use Only CSS Zoom - Disable Auto Fetch - Disable Font Face - Disable Range - Disable Stream
