‘insecurely-downloaded’ files are a risk to users’ security and privacy. Google will eventually block them outright.
Beginning with Chrome 82, Chrome will warn users if they’re about to download mixed content executables from a secure website.
Google is estimating an October release for that build of the popular web browsing. Now, all mixed content downloads – a non-secure file coming from a secure site – will be blocked as of the release of Chrome 86.
This is part of Google’s effort to fully migrate developers over to HTTPS. Last year, Google began blocking https sites from pulling down insecure page resources.
Warnings are also coming to the Android and iOS versions of Chrome. But the above schedule will be delayed by a release for the mobile platforms.
