SuperFile Viewer 作成者: SuperFile

SuperFile Viewer connects sup.com to the SuperFile Viewer desktop app for Mac, which plays DRM-protected files with hardware-secure playback so a screenshot or screen recording of the content stays blank.

When you open a protected file on sup.com and choose "Open in SuperFile Viewer", this extension hands the file to the app through native messaging — one click, no browser prompt. Click the toolbar icon any time to check whether the app is installed and see its version.

The extension activates only on sup.com. It does not read page content, collect data, or talk to any site other than sup.com. The SuperFile Viewer app is a free download at https://sup.com/superviewer.
