Technical: Mac OSX / Java Applet Support in Mozilla Firefox

Technical: Mac OSX / Java Applet Support in Mozilla Firefox

Here I am trying to upload files to one of our vendors, but the upload icon is not appearing in Mozilla Firefox.

I looked all over, but no plugin.

I am thinking you ‘re killing me.  And, yes where did I look?

Well in Add-On Manager; specifically the Plugins Tab.

How to get there:

  • Menu Bar – Tools \ Add-ons..
  • Tab – Plugins

Goggled for help and confirmed that I am doing what I should be doing:

How do I disable Java in my web browser?
http://java.com/en/download/help/disable_browser.xml

Firefox
  1. Click on the Firefox tab and then select Add-ons
  2. In the Add-ons Manager window, select Plugins
  3. Click Java (TM) Platform plugin to select it
  4. Click Disable (if the button displays Enable then Java is already disabled)

But, I am thinking no Java Plugin.

Finally got some help:

Use the Java plugin to view interactive content on websites
http://support.mozilla.org/en-US/kb/use-java-plugin-to-view-interactive-content#os=mac&browser=fx21

Installing or updating Java

And, here are the steps I took:

  • Used Browser to access http://support.apple.com/downloads/#java
  • Downloaded Apple’s version of Java (javaForOSX2013-002.dmg).  
  • On Mac,  Accessed System Preferences \ Java \ Java Control panel
  • In “Java Control Panel” \ “Security” Tab – Ensured that “Enabled Java Control content in Browser” is checked
  • Restarted Browser, but alas still no Java.

BTW, that website (http://support.apple.com/downloads/#java) is not always accessible.

So what to do, but tightened up my Google Search.

I am thinking I need some music.  There is an old school rap track that says something about “… Just your luck, Greyhound is on strike”.  Tried it, but it is a bit of a downer.  DJ Quik -Tonite is also shown on same YouTube page.  And, I knew that will help.

Went back and Googled some more.  And, found:

MozillaLine – Java
http://kb.mozillazine.org/Java#On_Mac_OS_X

Found out a couple of things:

  • Mozilla is actively adding plugins to its BlockList

JavaAndFlashPlugins

So it appears that Mozilla is heeding to all this stuff coming from the “State Department” and actively blocking even recent Java Plugins.

The MozillaLine article led me to:

Information and system requirements for installing and using Mac Java 7
http://www.java.com/en/download/faq/java_mac.xml

So I am thinking I need the very latest java and that is available from:

Upon downloading Oracle’s java version and installing it, I am now able to use Java Applet’s (inside of Firefox).

Confirmation Steps

Apple – OSX – System Preferences – Other\Java – Java Control Panel

One can have a few different versions of Java JRE installed – You can have Oracle\Sun’s, Apples, etc.

Please make sure that the one enabled is Oracle\Sun’s 1.7._0_17

  • On OSX, access “System Preferences”
  • Access the Other sub-group, Java applet
  • Access “Java Control Panel”
  • Access the Java Tab
  • Click the “View…” button
  • Ensure that Oracle’s JRE is the only enabled option

Mozilla – Add-ons Manager

Ensure that “”Java Applet Plug-in Java 7 Update 17” is enabled.

  • Launch Mozilla
  • Menu Bar – Tools \ Add-ons..
  • Tab – Plugins

In the list of Plugins, you will see “Java Applet Plug-in Java 7 Update 17”

Conclusion

With BlockList and the like, it appears that Browsers are joining OS and Virus Security vendors in actively armoring their users.

For you, the user, and corporate help-desk, keep that in mind when you get support calls.

In terms of security and how it is effected, things appear to be changing all the time.

In an earlier post (https://danieladeniji.wordpress.com/2013/02/02/mac-osx-sunoracle-java-applet-typical-workspace-interaction/) on this subject, I concluded that I could not really get Java Applets to work inside Apple’s Safari Browser.  That is no longer the case, it works with the new Oracle\Sun JRE.

It might be that Apple has relaxed its security constraints on the above configuration.
