Basically, I would like Firefox to behave as if all responses from example.com carried the "Cache-Control: no-cache" header. I have searched the Mozilla addons site and there is a boatload of hits for "add http headers" but on closer inspection they all modify just the request headers. Perhaps there is another way of doing this, or maybe there isn't :-(


I don't know how to do it for an specific site, but this is the equivalent setting to IE's "Check for newer versions of Stored Pages: Every time I visit the webpage" in Firefox:

Type in the address bar about:config, then search for browser.cache.check_doc_frequency. Set its value to 1, which means the website will always load the newest content every time you access it.

  • Yes, I know about that setting. But revalidating everything will be quite slow for complex sites. That's why I want a solution (or rather a workaround) for a specific site. – Ian Zimmerman Oct 13 '15 at 5:56
  • I see. If you're developing a website or something like that you could just reload the site with "CTRL + F5". Otherwise I really don't know how. – LotharOne Oct 13 '15 at 5:59
