I have my firewall and manageable switch on the network with VLAN's set up. I did some testing and I found that it was something wrong with the firewall, not the switch:

When the switch is connected to the firewall, I can ping a computer in VLAN 2 while on a computer that belongs to VLAN 1.
When the switch is not connected to the firewall, when I try to ping from VLAN 1 to VLAN 2, I am unable to do so, which is what I want.

What do I need to configure on the firewall to stop the VLAN's from being able to communicate with each other?

You need to isolate the Layer 2 traffic between the VLANs with the Inter-Zone firewall, you can find an example here on this Endian tutorial:
