This wikiHow teaches you how to view a list of your browser's temporary internet files (stored cache data), which are pieces of data that help quickly load frequently visited sites. You cannot view temporary internet files on a mobile item...
Method 3 of 6:
Firefox

Open Firefox. Firefox's icon resembles a red-and-orange fox wrapped around a blue globe.

Click the address bar. The address bar is at the top of the Firefox window.

Type about:cache into the address bar. This command opens and displays the temporary internet files.

Press the ↵ Enter key. Doing this will open the "Network Cache Storage Settings" page.

Click the "List Cache Entries" link. It's below the "disk" heading near the middle of the page. Doing so will open a separate tab with all of your Firefox's temporary internet files listed.
