Firefox Version 52 Blocks JRE and, thus, EBS Forms

Firefox's recent stable release channel version 52.0 update ends NPAPI plugin support for Java, Microsoft Silverlight and Adobe Acrobat (Adobe Flash is not affected, however, no support end date for this plugin has been communicated). The impact for Oracle E-Business Suite (EBS) customers using Firefox is that even though they have the latest version of Java installed on their system, Firefox will not recognize and load the associated Java plugin. 

A morsel of good news for Firefox-EBS users is that a temporary workaround does exist for those who still want to utilize the Firefox browser.

This workaround solution involves uninstalling the version of Firefox that is on the stable release channel (for Firefox 52 ESR version you just need to install it and do not have to uninstall the stable release channel version) and replacing it with a version of Firefox that is on the Extended Support Release (ESR) channel. The Firefox 52 ESR version will continue to support NPAPI plugins until early 2018. As always, EBS customers can continue to use the Internet Explorer (IE) browser which does not have Java compatibility issues. 

Information detailing the above information is on the Mozilla Support site

You may have experienced an automatic upgrade already and are wondering what to do to re-enable a working version of Firefox. Click here to download Firefox ESR. After you install this version, if you go to Help, About, you will see "You are currently on the esr update channel."

BTW and regardless of version, for Windows, EBS only supports the 32-bit version of Firefox. So, when you click the link above, find your language and click the link in the Windows column (not the Windows 64-bit) column.

The only drawback to running this version (as opposed to Version 51), is the annoying message below User Name and again below Password. Once you are logged in, the message does not repeat.

Alternatively, you can download and reinstall Version 51 from Firefox version 51. Click the top link. 

Steven Chan's Oracle E-Business Suite Technology blog of March 13, 2017, explains this further.

When in doubt about any browser issue, version or setting, the definitive source is My Oracle Support note 389422.1 – Recommended Browsers for Oracle E-Business Suite Release 12 and note 393931.1 – Deploying Sun JRE (Native Plug-in) with Oracle E-Business Suite Release 12.

FYI: On 24 April, 2017, Steven Chan posted that Java Web Start is now supported on EBS R12.1 and R12.2.

Java Web Start is (basically) the replacement technology for NPAPI (or NSPAPI) and should allow you to use Forms with MS IE, MS Edge, Firefox, Firefox ESR, and Google Chrome.

Moving to Java Web Start will require you to apply some patches and make some configuration changes.

See MOS 2188898.1 and the blog posting below for more information.
