FirePod was renamed the FP10.
FP10 can be found in the Discontinued Products in the Download section of the Support Page.
On the FP10 Download page, select your OS to find your drivers.
If there are no drivers posted for the OS you are selecting, we most likely don't support that OS for that device.
In your case for 10.7.5 there are drivers posted.
Go to this link to get started and be sure to pick your OS in the drop down where prompted.
