Firefox 52.0 ESR - Java plugin is not showing up on the plugins page.

more options

I downloaded Firefox 52 ESP to try and enable the java plugin. I had Java installed beforehand. However, even on this version, when I go to Options -> Extensions & Themes -> Plugins. I wanted to know if there is any way to actually install the Java Plugin, and if not, what version of Firefox would allow for that. Thanks.

Did you install Firefox 52 ESR from here:

https://ftp.mozilla.org/pub/firefox/releases/52.9.0esr/

Note that 32-bit Firefox is required, you can't run the Java plugin in 64-bit Firefox.

The old Java test page is here:

https://www.java.com/en/download/installed.jsp

Does it let you download?
