Firefox 4 couldn't find compatible plugins, but didn't say in the final message, which ones it had failed to find. I've reinstalled 3.6.17. Is there a way to discover which plug-ins were lost?

I was exhorted to upgrade to Firefox 4. Believing that like most such upgrades, it would be compatible and inconsequential, I did so. Having completed installation, it told me that a couple of plug-ins were incompatible (Yahoo and another which I didn't note) and that it would search for compatible plug-ins. When it finally told me that none were available, it didn't then say which were not installed, so I had no way of going back to find out. I followe instructions on a previous question to uninstall FF4 and reinstall FF3.6.17. How can I now discover which plug-ins were lost and thus restore them?

You can set the prefs dom.ipc.plugins.enabled.* to false on the about:config page to disable the plugin-container process.
dom.ipc.plugins.enabled.npctrl.dll (Silverlight)
dom.ipc.plugins.enabled.npqtplugin.dll (QuickTime)
dom.ipc.plugins.enabled.npswf32.dll (Flash)
