The "about:plugins" page does not update the plugin version information when the Java plugin is installed manually from a JDK that is already installed on the computer.

Reproducible: Always

Steps to Reproduce:
1. Install Java plugin from JRE 1.5.0:
  ln -s /opt/java/jdk/1.5.0_05/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox-2.0.0.1/plugins
2. Start firefox
3. View URL "about:plugins"
4. Remove symbolic link created in step 1.
5. Restart firefox
6. View URL "about:plugins"
7. Install Java plugin from JRE 1.6.0:
  ln -s /opt/java/jdk/1.6.0/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox-2.0.0.1/plugins
8. Restart firefox
9. View URL "about:plugins"

Actual Results:  
In steps 3 and 9 the page displays Java plugin version "1.5.0_05-b05"

Expected Results:  
In step 9 the page should have displayed Java plugin version "1.6.0-b105"

To correct this the user must edit manually the $HOME/.mozilla/firefox/pluginreg.dat file (which says "do not edit" on the first line) and remove all information about the Java plugin.

10. Edit Remove all information about Java plugins from 
11. Restart firefox
12. View URL "about:plugins"

Nevermind. I noticed that this happens only if the following conditions apply:
1. Java plugin version 1.5.0 was installed while using Firefox version 1.5
2. Java plugin version 1.6.0 was installed while using Firefox version 2.0
Apologies for the inconvenience.

I think you guys should reopen this because this still exists with firefox v18 and even with minor java updates. I'm running firefox v18 on centos 6 x86_64 and about:plugins shows :

Java(TM) Plug-in 1.7.0_09
File: /blue/global/apps/Linux/opt/jdk1.7.0_11/jre/lib/amd64/libnpjp2.so

Just to make sure I didn't somehow install the _09 jdk tar.gz into a directory called jdk1.7.0_11, i went to the java tester website http://www.java.com/en/download/testjava.jsp and it does indeed show 1.7.0_11 . I made sure firefox was completely closed before re-opening it, i checked lsof | grep java, grep jdk, grep jre to make sure nothing still had the old plugin opened from the previous _09 version I was running and nothing did, so this "bug" still exists and would be nice if re-opened.
