Currently, when a plugin on a page is for a type the browser doesn't know how to handle, we show a "click to download" placeholder that kicks off the PFS service. Unfortunately, all too often this seems to result in a PFS wizard that has no suggestions. It would be better if the browser consulted PFS in the background, and only offered the click-to-download UI if it knows there is an available plugin.

Bug 836415 has now removed the Plugin Finder Service (PFS) from Firefox. As a result, I'm closing all the remaining PFS bugs. If you're getting this bugmail for an ancient PFS bug, the basic summary of the world today is: * NPAPI plugins are a dying technology * PFS was already restricted to assisting with only the 4 most common plugins * Sites commonly provide their own UI for install a required plugin * Mozilla is generally focusing on improving the web platform so that proprietary plugins are not required. (Note that "plugins" are a completely separate from "browser extensions", such at those found on addons.mozilla.org. The latter are not going anywhere, and are not impacted by the removal of PFS.)
