Please try this workaround. For me, the plugins like Java and VLC came back after doing this. I'm using Ubuntu 16.04 64 bit with Mozilla Firefox 64 bit version 52 (not ESR) and Java JDK 1.8.0_112
- Open Firefox and type about:config in address bar and press enter
- Click 'I accept the risk!'
- Right click anywhere and select New>Boolean
- Type plugin.load_flash_only in the box that appears
- Set the value to false
- Clear all history and restart Firefox
I'm also using various Government websites which uses java plugin and Digital Signatures.
Try this and let me know.
Edit: Mozilla Firefox 53 will remove the flag plugin.load_flash_only
so that this workaround won't work anymore.
Pale Moon web browser team announced that they will continue the support of NPAPI plugins indefinitely. To install java plugin in Pale Moon, run this in terminal
sudo ln -s /usr/lib/java/jdk1.8.0_121/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/libnpjp2.so
I've tested java plugin in Pale Moon browser. 100% working.

Note: if you want to upgrade afterwards, launch it with
gksudo firefox
, and chooseHelp > About Firefox
menu, and see if any updates are available. If yes, apply them.
