Stories similar to Java not working in Firefox after Java upgrade

why does this page say java is running if I don't have the java plugin installed? How do i find and disable the java plugin for firefox, and others?

This is my first post; sorry if I make mistakes.

It seems that there is no way for me to install java plugin in firefox 3.6. I've already read some threads about similar problems but none of the solutions that worked for other people work for me. So I decided to open a new thread.

Hi,I've successfully installed the sun-jre version of the Java plugin, which correctly shows as "Java TM plug-on 1.7.0_11" as an Iceweasel plug-in. Mozilla's site shows that this is the current Java plugin.

In my ubuntu 10.04LTS jre is installed and the commands 'java' and 'javac' are working but firefox is not showing java applets. I have tried following command:

Code: ln -s /opt/java/32/jre1.6.0_30/lib/i386/libnpjp2.so ~/.mozilla/plugins/ But a broken link is created since there is no such source file.

As far as I can see, gcj-jre-headless and gcj-jdk are installed.

Please help.

I'm on a CentOS 6.2 machine and I'm trying to switch from the Sun Java 6 plugin to the Oracle Java 7 plugin. When I execute the alternatives command it only displays the Java 6 path. What... [by kev833]

I installed the Java 1.4.2_19 JRE, SDK, and Mozilla plugin in SCO (OpenServer 5.0.7). However, every time I try and view the java console, the browser immediately closes.

OK... sort of at a loss. Java "was" working great, until today? as far as I know, it's working, but not on FireFox nor Chrome. Both say they "Cannot load Java(TM) Plugin 1.7.15."

I have OpenJavaJDK's 6 and 7 (default). Oracle JDK and JRE version 7... NetBeans and Eclispe JEE.

F17 java issues 43 weeks 3 days ago

I had trouble with java applications running in browsers (google chrome and firefox) so I updated java. However, the only result was that both firfox and google chrome claim that java is not installed. I tried reinstalling java but again that did not work.

I have tried enabling java via browser settings but java doesn't even appear as an option.

Problem with java3d 31 weeks 2 days ago

I want to play this java simulation: http://www.compadre.org/OSP/items/detail.cfm?ID=9640 in java 3d mode on a linux (ubuntu) system. But it doesn't work.

If I switch to java 3d-mode it complains that java 3d is not installed. sudo aptitude install libjava3d-java didn't help.

Then I did a right click in this java app and selected Diagnostics-> About Java 3D.
