Turn off cache in FireFox when your Testing

Just a quick tip for those out there that keep doing “Clear Browser Cookies, Cache, Everything…” you can turn it off completely in Firefox while your doing development and testing.

METHOD 1: in settings


I add Here’s how to disable FireFox’s browser cache completely.

  • Fire up FireFox
  • Type about:config in your address bar (click I’ll be careful)
  • Type ‘cache’ in the search bar, and look for network.http.use-cache, and double click it to set it to false. Double clicking it again will set it to true and re-enable the cache …and then you’re done.
  • To forcibly reload a page and all its dependencies, direct from source, ignoring local and proxy caches hold the shift key and hit reload.
  • This applies not only to FireFox but also IE6/7 and Safari (maybe others too). I have a feeling this may be a ratified standard.

METHOD 2: bypass

You can reload the page and bypass the cache with:

  • Press and hold Shift and left-click the Reload button.
  • Press “Ctrl + F5” or press “Ctrl + Shift + R” (Windows,Linux)
  • Press “Cmd + Shift + R” (MAC)
  • See Keyboard shortcuts – Perform common Firefox tasks quickly and Mouse shortcuts
  • Firefox also has a memory cache, but disabling the memory cache isn’t recommended and can cause problems.
  • If you run in Private Browsing – Browse the web without saving information about the sites you visit mode then also the disk cache is disabled but also other features like permanent cookies and history are disabled.
