According to SlashGear, Google has begun to warn Chrome users about non-HTTPS downloads from HTTPS pages, which they call “mixed content downloads”. However, starting June this year, it will also block files little by little in an attempt to get website developers to fix things before they break.
Insecure web pages can potentially steal sensitive data that is input by a user very easily, however, this is not explicitly the case as hackers can also be very good at stealing data even with secure pages. Although this new feature will highlight insecure web pages and will help people to avoid dangerous downloads, the best advice is for people to think twice when inputting any sensitive or personal data on any webpage.
Research into a website is paramount should it ask for personal information. Webmasters should seriously consider upgrading their sites too as not doing so can harm their search engine ranking.
