Thank you for for the b.m.o reference, it's now clear what we are doing wrong:

"304 Not Modified responses that are a result of a UA-generated conditional
request MUST be presented as 200 OK responses with the appropriate content.
Such UAs MUST allow authors to override automatic cache validation by setting
request headers (e.g., If-None-Match, If-Modified-Since), in which case 304 Not
Modified responses MUST be passed through."

It is the second part (overriding the automatic cache) that is not supported.
It would good to know the reasoning behind this requirement, but in any case,
we should definitely follow the spec and Firefox here.
