This quote applies

"7.  Where is the mail client? 

Firefox works with whatever mail client is the default on your system.
However, we recommend Mozilla Thunderbird, our next generation email
client and the perfect complement to Firefox."

Note it says it uses the default mail client.  However, there are other
ways.
