NPAPI plug-in for Mac Conference Client

Are there any variations in the plugin file name, MIME types, description, or version from one release to the next?

Windows: Version rarely changes. However it still might change in new release. MIME type doesn’t change.
Mac: Version changes with every release. MIME type changes according to version (e.g. application/x-confclient_dispatcher_0.36, application/x-confclient_dispatcher_0.37 etc.)

Are there any known security issues in current or older versions of the plugin?

Additional Information:
We plan to remove the use of NPAPI in our client installer in our next major version release
Ever confirmed: true
Whiteboard: application complete
We believe that the correct experience for this plugin is not automatic activation, especially because this updates client software on the user computer. The application is not accepted.

Resolution: --- → WONTFIX
As this is a temporary solution, and our application only changes our own software, that too only after asking the user and getting his/her approval - we will absolutely do nothing unless the user confirms - can you please elaborate why the request was rejected?
Can you please explain again why the request was rejected? thanks
In general, we believe that users should explicitly opt-in to additional software running in their browser. In this case, users can do that via the plugin activation prompts, or you can package the plugin in a Firefox extension for users to install/accept. Once the user has accepted the plugin via "Always Enable" on a domain, it should continue working.

The whitelist is a Firefox mechanism to temporarily bypass this requirement for certain, especially while they are transitioning to a native HTML solution. But in this case the user impact is minimal and the builtin plugin activation UI is better.
