For as long as I can remember, only Adobe Flash Player and Silverlight are known, while Google Earth Plugin, iTunes Application Detector, Picasa, Microsoft Office 2010, and Google Update are always reported to me as unknown. These latter five strike me as plug-ins that are not obscure and are likely to be in lots of users' browsers, and further, that they are provided by companies who would likely provide straightforward ways to perform automated checking of version numbers. I grant that Mozilla cannot be expected to keep up with every conceivable plug-in, but it seems to me that, if the page/service is going to be helpful (and worth featuring in the newsletter, and so on), then some more effort should be put into it. As the old saying goes, anything worth doing is worth doing right. If this is a case of "we know what has to be done, it's easy, but we just don't have the person-power," I'd be happy to volunteer my help.
