Q: When I use Firefox's Responsive Design View, the images aren't automatically reloading when I resize the window. What do I do?
A: This is a known bug that only affects Firefox version 38. If you update to Firefox 39 or later, this should be resolved (at the time of writing, Firefox 39 is slated for release June 30, 2015).
