Under what conditions does the firefox honor / headers cache expire

Firefox caches video in 10 sec 1.5MB format, but not 50sec video with 8.5MB. I guess it is due to file size, but I'm not sure. Under what conditions does firefox execute cache requests?

I use this code to force caching of web files:

<FilesMatch "\.(webm|ogg|mp4)$">
Header set Expires "Mon, 27 Mar 2038 13:33:37 GMT"
Header set Cache-Control "max-age=864000"
</FilesMatch>
AddType video/webm .webm

There are two different questions. HTTP cache headers can never indicate that the user agent should cache the resource, only that it should not cache the resource. Thus, Firefox, not caching your video, does not , without observing the headlines.
