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

turn-off-cache 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.

Frequently Asked Questions (FAQs) about Turning Off Cache in Firefox for Testing

How can I disable cache in Firefox for testing purposes?

Disabling cache in Firefox for testing purposes is a straightforward process. First, open your Firefox browser and click on the menu button, which is represented by three horizontal lines at the top right corner of the browser. From the drop-down menu, select ‘Preferences’. In the ‘Preferences’ tab, click on ‘Privacy & Security’ on the left-hand side. Scroll down to the ‘Cookies and Site Data’ section and check the box that says ‘Delete cookies and site data when Firefox is closed’. This will ensure that your cache is cleared every time you close your browser.

What are the benefits of disabling cache in Firefox for testing?

Disabling cache in Firefox for testing can provide several benefits. It allows developers to see the most recent version of a website or application, ensuring that any changes made are accurately reflected. This can be particularly useful when debugging or troubleshooting issues. Additionally, disabling cache can help to improve the performance of your browser, as it reduces the amount of data that needs to be stored and processed.

Can I disable cache in Firefox permanently?

Yes, you can disable cache in Firefox permanently. To do this, follow the same steps as above, but instead of checking the box that says ‘Delete cookies and site data when Firefox is closed’, check the box that says ‘Always use private browsing mode’. This will ensure that your cache is always disabled, even when you restart your browser.

Disabling cache in Firefox prevents your browser from storing any new cache data, while clearing cache removes any existing cache data that has already been stored. Both can be useful for testing purposes, but disabling cache is generally more effective as it ensures that you are always seeing the most recent version of a website or application.
