That sounds like a warning from NoScript. If you have that extension installed, either authorize that site in the permissions list of the extension or disable the extension.

Could be Firefox Cross-Origin Resources
NoScript usually warns on cross-site scripting.

Firefox 52.6.0 ESR should work as well with Java applets and that version is still supported, so no need to use Firefox 38.

Why-do-Java-Silverlight-Adobe-Acrobat-and-other-plugins-no longer work.

^Note for Windows users you need the 32-bit Firefox 52.6.0esr to use the Java Plugin as the Win64 Firefox 52 ESR only allows the 64-bit Flash Player and Silverlight tPlugins to run.
