qBittorrent Companion от lokaur

Just right-click a magnet link on any webpage and select Add to qBittorrent — the torrent will be sent directly to your qBittorrent server without opening the qBittorrent WebUI.

For the extension to communicate with qBittorrent, CSRF protection must be disabled in the qBittorrent Web UI.

Open Settings → Web UI → Security and disable Enable Cross-Site Request Forgery (CSRF) protection.
