How to Disable Cache in Mozilla Firefox?

You may permanently disable the Firefox cache without worrying about leaving the Developer Tools window open. A Firefox add-on also exists that, with a single click, entirely removes the cache. I’ll demonstrate both approaches.

Disable Firefox cache

Firefox is a constituent of a select group of browsers not built on the Chromium platform. Despite this, Firefox also features a menu which is called Developer tools and some hidden options that you may use to disable the cache quickly. Read further to know how.

Adjust Firefox AutoConfig

Using the advanced menu in Mozilla Firefox, you may personalize your experience in browsing. This menu also includes a deactivation option for the browser cache.


This is how you get to this menu.

  1. Open Firefox and open a new tab. In the top address bar, type about: config and hit Enter. Use the Accept the Risk and Continue buttons to proceed.
  2. Now put browser.cache.disk.enable into the search box, double-click on the resulting link, and set its value to false by clicking on it twice.
  3. Now, open Firefox again after closing it. Use the same methods above to change the browser’s setting.memory.cache.enable set to false.

That’s it. Firefox will no longer keep any cache details on your device.

Use Developer Tools

You can also disable the cache in Firefox through the Network settings in the Web Developer menu, much like in Chrome.

  1. Open Firefox on your computer. To access more tools > Web Developer Tools, click the three lines on the top right.
  2. There, select the Network tab and mark the Disable Cache checkbox.

I’m done now. Firefox will no longer save cache details until you close the Developer menu.

Using preferences, disable Firefox cache

To deactivate local cache storage in Firefox, you must disable two settings in the preferences. This is how:

  1. In the Firefox address box, type about: config and press Enter. A warning notice will appear; you must acknowledge it to continue.
  2. Copy/paste each of these preferences into the search field, then change each value to False, browser.cache.disk.enable, browser.cache.memory.enable
  3. After that, Firefox will cease utilizing the cache if you restart the browser. With the first choice, Firefox is prevented from saving cache on the hard drive, and with the second, it is prevented from storing cache in the computer’s memory. This basically turns off the cache.

Employ a Firefox Add-on

It is significantly simpler and quicker to deactivate caching using a Firefox extension. Let’s say you frequently need to enable or disable caching. In such a situation, I’ll advise utilizing a specialized extension because having to repeat the aforementioned procedure each time you need to set or disable the cache might be highly time-consuming.

The Toggle Cache add-on, which enables/disables Firefox cache with a single click, is ideal for this purpose. You can enable or disable the cache anytime by clicking the Toggle Cache symbol in the top bar.

Here is an alternate way how you can disable the Firefox cache

For those who can afford a monthly unlimited internet connection, caching web page elements like style sheets, javascript, and photos tend to help websites load quicker while saving plenty of bandwidth.

The only way to fix this is to permanently turn off my browser’s caching features, Mozilla Firefox, while I’m coding.

  1. Type about: config into the address bar of Mozilla Firefox after opening it. (If a warning appears, accept it to proceed.) In the Filter section, enter the network. To convert the value from True to False, double-click on http.use-cache.
  2. What you see below is the new setting. You’re good to go after restarting your browser. Just repeat the preceding procedures and set the value back to True if you want to enable or activate the caching mechanism.
  3. If this doesn’t work for you, you can reload the page while pressing the Shift key on your keyboard.


Firefox provides the most straightforward method for turning off caching among these browsers. The implications of disabling the cache are permanent, so it’s less of a bother in the long run, even though you have to access the hazardous preferences to do so. Use a third-party plugin if you frequently need to set or disable caching since it simplifies the procedure and allows for a one-click operation.
