I'd vote for WONTFIX.

+1 to WONTFIX - this will break lots of things. 

Comment 3

I should qualify that; responses with Cache-Control: no-cache can be cached, but they need to be revalidated before being served. 

So, it's perfectly acceptable to store something with no-cache on it in the cache, to allow it to be revalidated (or perhaps used offline) -- no extra preference would be needed to do that. It's not so much a matter of ignoring no-cache, as it is of taking advantage of the full semantics of no-cache.

I think it lets Firefox be more usefull in "work offline" mode.
In roadmap of Firefox 3 there is point about cache.

Comment 5

[Brian Smith (:briansmith, :bsmith, use NEEDINFO?)]

I agree with Mark in comment 3. Regarding better support for offline mode, I am sure there is already a better bug for that, and I agree that is something we should do, but we should be doing that without the need for the user to set a preference.
