I think I might have answered part of my question whilst going to download 
a Knoppix dvd.  In addition to downloading ISO and MD5 checksums, you can 
also get a .ASC file, which contains a digital signature--containing Klaus 
Knopper's PGP key in this case, intended to verify the authenticity of the 
ISO as coming from him.

Why Firefox would want to "execute" such a file at startup, I'm still not 
entirely sure, but if the file is indeed the same type as above, this 
would explain why Firefox identified it the way it did.
