Is IDM Integration Module safe?

Clean risk

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.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
