Sub Tasks

Description
This CR is for addressing JIRA RT-16581.

the machine has both 6u26 and 7 java plugin registered:

@java.com/JavaPlugin,version=1.6.0_26
@java.com/JavaPlugin,version=10.0.1

FF will go through the MozillaPlugins reg. keys in alphbetical order and will attempt to load the dll in that order.
Without the 1.6.0_26 key, FF will use the jre7 version of java plugin.

This bug will need to be fixed in the fx installer.

During install, fx installer should update the @java.com/JavaPlugin reg. key instead of adding a new one.
During uninstall, fx installer should update the @java.com/JavaPlugin reg. key to point to the remaining latest version of java plugin on the machine.

Comments
EVALUATION

Fix in fx installer including the following:

1) remove all @java.com/JavaPlugin registry keys before registering the current plugin version;

2) check if current plugin is registered. If it is, remove all @java.com/JavaPlugin registry keys before re-registering the remain java plugin on the machine;

3) for older java plugin version, don't append version info (,version=x.y.z) to the @java.com/JavaPlugin reg. key;

4) corrected MIMEVERSION for older JRE which should be the same as the JRE version.
