Deleting stored data from your Web browser can be a good way to keep your browsing activities private, clear up some storage space on your device, and troubleshoot problems that you are having when trying to view a website. The Firefox browser on your iPhone allows you to delete different types of stored data, including the cache.
Our tutorial below will show you where these options are located so that you can delete the cache as needed. You will be able to turn off the options for other types of stored data if you wish to keep them, or you can choose to clear any combination of data types that you wish.

Step 3: Swipe to the left on the first pop-up menu.
Step 4: Select the Settings option.
Step 5: Scroll down and choose the Clear Private Data option.

Step 7: Touch the OK button to confirm that you understand this data cannot be recovered once you complete this process.
