Why am I getting the security warning: Allow access to the following application from this web site?

This article applies to:
  • Java version(s): 7.0, 8.0
SYMPTOMS

When trying to access any website or webpage, a security warning dialog appears:
Allow access to the following application from this website?
This website is requesting access and control of the Java application above. Allow access only if you trust the web site and know that the application is intended to run on this site.

Live connect JavaScript call Security warning message

CAUSE

The website uses JavaScript code in conjunction with the Java application. This message is shown to alert you of a possible security concern because the website was not explicitly granted access permission by the application.
SOLUTION

Allow access only if you trust the website and know that the application is intended to run on this site.

Options
Do Not Allow (recommended): Prevents the website from accessing and running the Java application. This may cause unexpected behavior by either the website or the application, but adds a measure of security to your system and files.

Allow: Permits the website to access and control the Java application. This could potentially compromise the security of your system.
