Is Free Download Manager official extension safe?
Free Download Manager captures HTTP headers and cookies for all browsed URLs and sends them to the local FDM app via native messaging.
The extension intercepts all outgoing and incoming web request headers across every site visited, including Cookie headers, and transmits them to the FDM native host (org.freedownloadmanager.fdm5.cnh) running on the user's machine. When a download is detected, it also collects all cookies for that URL and passes them to FDM to authenticate the download on the desktop side. A one-time install check reads open tab URLs and up to three recent history entries to determine how the extension was installed, but this data is not transmitted remotely.
