Oracle Forms on Firefox 52 desupported NPAPI plugin

March 9, 2017

Today everyone got the very scary news that Firefox will no longer support Java applets. Well guess? It’s not news at all!

It’s just another attempt to scare poor Form’s users into to getting them to do a million dollar multi year migration project. Well have no fear, because we have found not one BUT two very simple ways for you to continue to work with Forms for the year to come without worry.

The first is a very simple workaround, while the second is even better just upgrade to Forms 12c and do away with the browsers for good. So here are our options:

  • First, you can migrate to Oracle Forms 12c. Oracle Forms 12c comes with a very easy way of running Forms without the need for a browser. You could simply run Forms 12c from a Java application without the need for browser at all. Problem solved! You can see more information on that here!
  • Second, is a simple workaround we found for you all by going into the Firefox browser and switching off the new feature that disables the NPAPI plugin support. To enable to support in Firefox 52, we just need to turn on NPAPI plugin support by using the about:config functionality. Here is how it can be done.

1. Open a new tab in Firefox and enter the following text in the address bar:


Confirm that you will be careful if a warning message appears for you.

Create a new boolean option and name it plugin.load_flash_only


2. Set the plugin.load_flash_only option to false.

4. Restart Firefox.

Note: With Firefox 53, the ability to restore NPAPI plugin support will be removed completely.

So no fear at all!!
