The proxy setting has to be configured in the web browser so that all http traffic is routed through the localhost proxy at port 8800. Firefox users would click on Tools > Options > Advanced > Network > Settings to open the proxy configuration.

They would then select the manual proxy configuration and enter localhost and port 8800 under HTTP Proxy. They should make sure to revert the settings to No Proxy again when they stop using Freezer.

The program requires the user’s presence because the download dialog will pop up whenever the user clicks on play on any of the supported music portals. This works nicely with the various radio stations at Deezer and playlists in general.

Downloads are pretty fast, they never took more than a few seconds during tests. Freezer is probably best for users who like to download a few selected songs from those music portals. Should work nicely with an instant proxy changer or autoscripts that automatically save the files.
