Enable java applications in Firefox 52 and above

I was trying to use Phylowidget (http://www.phylowidget.org/), which is a great tool to edit phylogenetic trees (i.e. regrafting branches to other branches):



The problem is it doesn't seem to work anymore!

Why? Simply because Firefox 52 now blocks every plugins except Flash:
https://www.java.com/en/download/help/firefox_java.xml
https://blogs.oracle.com/java-platform-group/entry/launching_web_start_applications

Here is a solution to allow Firefox to use others plugins than Flash:

1) Go to main menu Apple -> System Preferences, then Java (very bottom).
Then go to Security panel, and add the url http://www.phylowidget.org/ to the Exception Site list.
 
Here is my parameters:



2) In the Firefox title bar, write:
about:config
=> select: I accept the risk!

3) To the very right of the list, do right-click and select:
New>Boleean

Then write: plugin.load_flash_only

And set it to "false".

4) Restart Firefox and finally go again to Phylowidget (http://www.phylowidget.org/).
 
Now it should work. And this should be similar step with any other java applet, such Jalview (http://jalview.org/).
