Is IDM Integration Module safe?

IDM Integration Module reads cookies for every download URL and forwards them to the local IDM desktop application over WebSocket or native messaging.

When a user initiates a download, the extension collects all cookies associated with the download URL via browser.cookies.getAll and transmits them to the IDM desktop application at ws://127.0.0.1:1001 or via the native messaging host com.tonec.idm. This allows the desktop downloader to authenticate the request as the browser user. Additionally, on startup the extension sets a persistent numeric client identifier cookie (idmwebext_cid) on internetdownloadmanager.com with an expiry of January 2038.
