To clear the cache on your Mozilla Firefox browser, follow the steps below.

(We used Mozilla Firefox version 11 to create these instructions, but the principal should be the same for all versions of Firefox.)

Step 1: Get Started

Open Firefox on your Windows computer.

Once your browser is open, press Ctrl+Shift+Delete to open up the Clear All History window.

Alternatively, you can manually go to this menu by clicking the Firefox menu in the top left corner, select the right arrow next to History and click Clear Recent History.

Step 2: Clearing Cache

Click on Details to expand the list.

Ensure that the Cookies, Cache and Site Preferences boxes are checked.

Note: This is necessary to completely clear your cache. Uncheck everything else to avoid deleting data unintentionally.

In the Time Range to Clear: drop down menu, select Everything.

Select Clear Now to proceed.

Step 3: Cache Cleared

Congratulations! You've now successfully cleared all your Mozilla Firefox's cookies & cache data from your computer!

Note: If you do not see any difference, kindly restart your browser.
