Internet Explorer - Out-of-date ActiveX control blocking

Internet Explorer (IE) has a new security feature, called ActiveX control blocking, to keep ActiveX controls, such as Java, up-to-date. This feature will prevent the app or web page from loading, if it finds that Java is out-of-date and will provide the option to update Java.

Java(TM) was blocked because it is out of date

When the ActiveX control blocks an older Java version, you'll see:

• In Internet Explorer: a notification bar, similar to Java(TM) was blocked because it is out of date and needs to be updated and options to Update or Run this time
• Outside IE: an Internet Explorer Security dialog, A website wants to open web content using an outdated program on your computer and options to Allow or Don't Allow running the application, as well to Update the old version.

Update Java

It is recommended you update Java before allowing the app to run. Click Update and download the latest Java version. If you don't trust the site or prompt, you can visit the java.com web site to get the latest version.

The out-of-date ActiveX control blocking applies to:

• Windows 7 SP1 Internet Explorer 8 through Internet Explorer 11
• Windows 8 Internet Explorer for the desktop

Firefox no longer offers a version which supports NPAPI, the technology required to run Java applets. More info

Firefox - Activate Java plug-in (Firefox 52 ESR and below)

Firefox implemented a new Click to Play security feature that protects against attacks, targeting plug-ins that are known to be vulnerable. This feature prevents applets from automatically loading and allows users to control what content they want to run or avoid.

• If you try to run a Java applet using a Java plug-in version that is identified as vulnerable, Firefox will prevent the applet from automatically loading and alert you that the plug-in is vulnerable.
• If an update is available, Firefox will provide the option to update or activate the plug-in. We recommend checking for updates before activating the plug-in.
• Additionally, Firefox provides an option to block or automatically activate the plug-in on a per-site basis.
