I’ve installed the Firefox extension “Flash Switcher” on my mac computer however I noticed that it only has flash players 9 and 10 available for testing. I read on the website that you can install other versions and it was saying to copy into a folder a file called NPSWF32.dll which apparently comes with every flash player installer.

I downloaded all the archives for the different flash players but there wasn’t one of these in the folder. I wondered if anyone knows where I can find it or how to install the different versions on the mac?

Currently in the folders are the following two files:

flashplayer.plugin  
flashplayer.xpt

But neither of these are in the downloads for the archived versions either.

Appreciate any assistance.
