about:plugins in Firefox 3.0.8 lists the Google update plugin npGoogleOneClick7.dll . It doesn't seem to be doing any harm but I'd like to prevent it from being loaded. Its in C:\Users\eric\AppData\Local\Google\Update\1.2.141.5 so it seems the only reason why its loaded is due to the plugin.scan.plid.all setting in all.js. The plugin scanning article warns that setting that false will disable Flash.
I'm surprised there is no way to create a preference to explicitly tell Firefox to ignore a directory when its scanning the PLIDs. Disabling the PLID scanning seems heavy handed.
The Flash - Firefox and Plugin scanning articles don't describe how to enable Flash if I set plugin.scan.plid.all false. Should I copy NPSWF32.dll and flashplayer.xpt from C:\WINDOWS\SYSTEM32\Macromed\Flash to the Firefox plugins directory? If that works do I have to do that every time I update Flash?
