How do I clear my cookies in Firefox?

First click on the "Open Menu" button.





Then click on the options button.




Then the privacy section.



Make sure that the mentioned settings are selected then click on the remove individual cookies link





Then you have 2 options either clear your cookies for just ScanPower (pictured [clear all ScanPower sites]). Or you can just clear all (all of your cookies are cleared when you close FireFox anyway).
