Can I buy FTM on MetaMask?

Excuse me, I have a question about cryptocurrency transactions. I'm wondering if it's possible to purchase FTM using MetaMask? I'm relatively new to this space and not entirely sure how the process works. Could you please explain the steps involved, if it's indeed doable? Also, are there any specific requirements or considerations I should be aware of before attempting this transaction? Thank you in advance for your assistance.
