SHA-256 support was first added to NSS version 3.8, which was released
on 10th April 2003. The map of NSS version to Firefox versions
doesn't even go back that far. However, looking at the Firefox release
history on Wikipedia, I'd guess that probably Firebird 0.7, released
in October of 2003, may have been the first to have that NSS version.
Anything called Firefox will support SHA-256.
Hope that helps,
