How do I cause Firefox to display only new data; not cached data. In particular I am concerned about old data in all interstitial locations such as Content Delivery Networks (CDN) that have what appears to be old webpages and their associated streaming video. How do I know the content is old? I inferred it from the date visible on the webpage.
Edit: The CDN cache is not the same thing as my Firefox cache, so this is not a dupe question.
