Is AB Download Manager Browser Integration safe?

Clean risk

AB Download Manager Browser Integration forwards cookies and request headers for download URLs to the locally installed desktop app.

When a download link is triggered, the extension reads cookies for that URL via chrome.cookies.getAll and captures any Authorization or Cookie headers from the intercepted request. This data is sent via HTTP POST to the AB Download Manager desktop app listening on localhost (default port 15151). The sendHeaders option, enabled by default, controls whether cookies and headers are included in the handoff.

Shared hosts - 2 hostnames

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.
