Users can still choose to load page anyway
In a post on Google's Chrome support site, the company explains that current browsers only notify users after the insecure scripts have been allowed to run. If the sites happen to be compromised by an attacker using the insecure scripts as an exploit, the damage may have already been done by the time a user realizes that there is a security issue.
Rather than highlighting mixed script sites with a red 'https://' in the location bar, Chrome 14 blocks sites from running any scripts that are not also protected by HTTPS. Users may notice that some sites do not properly display, however the browser will provide a "Allow Anyway" option for bypassing the protection system. The browser also includes a mechanism for notifying site owners of potential problems. [via Google Operating System]
