Firefox. There are two separate issues here:

1. Whether Firefox should read the external DTD subset.
2. How it should treat unrecognized entities when it doesn't read the 
external subset.

Let me check the spec, but my recollection is that if the external DTD 
subset is not read, unrecognized entities are not a fatal error.
