Is there some way to install Jave only on my USB drive. You can read the full path where the default firefox plugin is placed. The [portable java plugins folder]. Support Forum; Firefox; install java plugin without internet. Support Forum. Where can I download the plugin and how do I install it on the stand alone machine? I need to install the java plugin for java 1.7.55 on a maching that does net have internet access. Where can I download the plugin and how do I install it on the stand.
I am trying to install Java and plugins for Firefox. I installed both the JDK and JRE.
When I try with the sudo update-alternatives --config java command it shows only one choice available.
Plugins are not usable in Firefox.

If you are using a version after 52 (not ESR), which disabled NPAPI, you are out of luck. If you are using one prior, which you absolutely wouldn't want to, you can install the OpenJDK JRE, which would allow you to execute Java binaries locally using the java binary. This however, isn't enough to execute Java web applets on your browser, which can be accomplished by installing the Icedtea plugin:
Then go to about:addons, in the plugin section, check if the plugin is enabled. Mozilla disables insecure plugins by default, that means that Java is disable even after installation due security concerns. You need to activate it before using it.
Installing the IcedTea Java plugin:
To install the IcedTea Java plug-in, open a terminal and type:
Install the Firefox plug-in - Oracle
In a terminal:
Remove the IcedTea plugin, if it has been installed.
Remove a former version of the Java plugin (may or may not be present)
Now you can install the plugin, by creating a symbolic link (you tell Firefox where the plugin is located). For 32-bit Java, use
For 64-bit Java use
Confirm that the JRE has been successful by using the official Oracle website.

Beginning in Firefox version 52, support for NPAPI plugins (java applets) in Firefox has ended, due to performance and security issues, the way that I manage to run java applets is to install the Extended Support Release (ESR) of firefox.

Java Download For Firefox
If you just downloaded and installed java jdk from oracle, then, let's say you have installed jdk-8u91-linux-x64.tar.gz on
/my/java/directory/
Then you'll have a directory like:
/my/java/directory/jdk1.8.0_91/
All you have to do is go to your ubuntu firefox plugins directory and create a link:
This is an old thread, but I stumbled upon it while googling a solution to my problem today. I figured someone else might be in the same situation.
I need in-browser Java for legacy work-related websites, and the oracle java plugin does not cut it. After a long trial-and-error approach, I got IcedTea working consistently in an older version of firefox like this:
- Download a tar of Firefox, version 51 (newer version don't support the plugin)
- Install the OpenJDK (7 or 8)
- Install the icedtea--plugin and the icedtea-plugin
- Now your openJDK installation will contain a IcedTeaPlugin.so file in the jre/lib folder
- copy this to the mozilla/firefox plugin folders (I couldn't figure out which one to copy it too, so I just copied it to anything firefox/plugins or mozilla/plugins)
- start your old firefox version
- verify the plugin is active (check about:plugins)
One of my colleagues created a script to remove the old firefox, and untar it on every run. That way it never gets updated accidentally. Be sure not to do this with your main firefox application.
I hope this helps you.
Its been a battle, especially since I went through this a couple of months ago with 14.04, forgot the solution, upgraded to 16.04...
It is different I had Iced-tea and Oracle working under firefox in 14.04. I actually prefer Oracle (not generally but my use almost requires it) so I only have that now. I did not attempt any multiple installs or repositories. Symlinks as per most of the instructions out there are no good either.
In the end, in Firefox went to Edit--> Preference-->Applications then scrolled down to the JNLP file extension and picked 'Use other..' from the drop down menu. Then found javaws from the relevant directory.

It is only a workaround, and Im not sure if it will suit your needs. Keep in mind most plugins will be deaded by March.
