The Web Developer extension for Firefox will present the response
headers for whatever resource is in the active tab. The option, 'View
Response Headers', can be found at the end of the Information menu.

I should probably note that the header output will not necessarily be
accurate, or a literal representation, at least when it comes to
multiple instances of a header. The most common difference will be that
the values will be combined into a comma-separated list. However, it may
also drop values in at least one rare case.

If you really want to know exactly what's being sent back, there's no
substitute, in my opinion, for telnet. :-)
