'''To completely clear the cache:'''
* In Firefox Quantum click the "Open menu" button (three stacked, horizontal bars in the upper right corner). Select "Options", then the "Privacy & Security" section. Go to the "Cookies and Site Data" subsection and click the "Clear Data..." button. Make sure the box for "Cached Web Content" is checked and click "Clear", (be sure the "Cookies and Site Data" box is unchecked if you do not want to clear this data as well).
* In versions of Firefox that display a single, orange "Firefox" button: click the "Firefox" button and click "Options". Select the "Advanced" section, and go to the "Network" tab, and click the "Clear Now" button. Then click "OK".
* When Firefox displays a menu bar, from the "Edit" or "Tools" menu, choose "Preferences" or "Options". Select the "Advanced" section, and go to the "Network" tab. Click the button called "Clear Now". Then click "OK".
* In SeaMonkey and later versions of Netscape, choose <code>Edit > Preferences…</code>, expand the "Advanced" section and choose "Cache". Click on the "<u>C</u>lear Cache" button.

If you would keep your data in your cache and test Wikipedia with an empty cache, you can use Private Browsing mode.
