I have a 64-bit Windows 7 installed on my system. I have 64-bit JDK 1.6.0_32 on the system. I also have installed 32-bit JRE version in my system. My Firefox is a 32-bit version. When i see the plugin page, the plugin page shows that the Java plugin is installed properly. However when I launch any pages with applets, they are not working. I am not sure if this is any settings issue or a bug in Firefox.
