We use JNLP in our web application to allow users to interact with a locally installed medical imaging software . Starting with Firefox 67, our users see a scary message that says that “0155073.jnlp” is an executable file. Executable files may contain viruses or other malicious code that could harm your computer. Use caution when opening this file. Are you sure you want to launch “0155073.jnlp”? They get this message every time they attempt to open an x-ray or a medical image. This message is alarming our users and causing much stress. How do you suppress this message or create an exception based on the site URL.

Thank you for your help.

There has been a pref (hidden from about:config) created to suppress this warning.

  • browser.download.skipConfirmLaunchExecutable = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

You need to create a new Boolean pref. Name: browser.download.skipConfirmLaunchExecutable Value: true
