Google is moving forward with its plan to block mixed content downloads from web sites to protect users from man-in-the-middle attacks. Google states that they are blocking these types of downloads as they are a risk to a user’s security and privacy. The feature will be gradually rolled out in the following upcoming Google Chrome releases. Google has an experimental flag titled ‘Treat risky downloads over insecure connections as active mixed content’ that can be enabled in Chrome 80 and later. For Android and iOS users, the rollout will be delayed by one version with warnings starting in Chrome 83.
