title: mozilla firefox ignoring the cache-control header
body: <p>I am loading a few thumbnail images in my application which are stored on google cloud, I have made the thumbnail objects public and set <code>cache-control: public, max-age:2628000</code>, this seems to be working on chrome where i see the images are getting loaded from cache but on mozilla firefox this is not working, <strong>whenever i reload the page</strong>, I always see the images are been request from the server. I have also checked that I do not have <code>disable cache</code> checked in developer tools
  here is a screenshot </p>
