Engye Drive Mount от Pavel Safronov

Engye Drive Mount lets Firefox reach the Engye Drive Mount desktop app so your phone appears as a real network drive on your computer (Finder on macOS, File Explorer on Windows, a folder on Linux).

Firefox blocks web pages from connecting to http://127.0.0.1 as mixed content, so this extension performs the local connection the web app can’t. Click the toolbar icon, scan the QR code with your phone, and the drive mounts.

How it works

Phone ↔ desktop transfer over WebRTC (peer-to-peer)
End-to-end encrypted (AES-256-GCM); nothing is stored on or routed through our servers
No account, no analytics, no tracking

Requires the free, open-source engye-drive-mount desktop app running locally (npm install -g engye-drive-mount). Source: https://gitlab.com/PavelSafronov/engye
