I have installed Mozilla Firefox 14.0.1, for Linux, but I'm having trouble seeing the Java 'plugin' (libnpjp2.so').

I believe I'm running Red Hat Enterprise Linux on a 32 bit machine, as detailed :- Linux localhost.127.0.0.1 2.6.18-128.el5PAE #1 SMP Wed Dec 17 12:02:33 EST 2008 i686 i686 i386 GNU/Linux

I have installed the 32 bit version of Java :- [root@localhost /]# java -version java version "1.7.0_05" Java(TM) SE Runtime Environment (build 1.7.0_05-b06) Java HotSpot(TM) Server VM (build 23.1-b03, mixed mode)


from the 'pluginreg.dat' file I see :- [INVALID] /root/Oracle/Middleware/jdk160_11/jre/lib/i386/libnpjp2.so:$


I'm referencing the 'Oracle' version of 'libnpjp2.so', as this appears to be the 32 bit version, and I'm trying to configure Oracle APEX on this version of Linux.

I think I need to run Firefox in 32 bit mode, but don't know how, or if what I'm attempting to do is possible ?

Any feedback, would be most grateful.

Plug-in systems on Linux are nasty and buggy. The best thing you can do is uninstall Firefox and Java and try to reinstall them again by using your favourite package manager: Firefox first, Java then

The regular Firefox version as downloaded from the Mozilla server is a 32bit version

A 32 bit Firefox version only works with a 32 bit Java version and you need to place symlink to the Java plugin file (libnpjp2.so) in a location where Firefox finds it.

Did you try to delete the pluginreg.dat file to force Firefox to create a new file?
