Clearing Auto Complete

I currently switched from a PC to a Mac Book PRO and am having difficulty clearing the auto complete fields.

I know with a PC running IE its as easy as going to internet options, however running Mozilla on my Mac does not have this option.

Does anyone know how to erase the AutoComplete fields?

THanks in advance!
