Google proposed the addition of automatic blocking of high-risk downloads from non-secure websites in future versions of its Chrome web browsers. A proposal from Google Chrome security engineer Emily Stark in the World Wide Web Consortium (W3C) public mailing list. Chrome will tag executables or archives delivered over an HTTP connection initiated from HTTPS websites as mixed content and will automatically block them. Mozilla’s Daniel Veditz also expressed interest into adding this feature within Firefox. Google also revealed that they’re planning to also add automated blocking of all downloads initiated from ad frames which lack user activation.
