Did Pierre De Fermat *really* have a proof for Fermat's Last Theorem?

In 1637, Pierre De Fermat famously wrote in the margin of a copy of Arithmetica that he had proof that no three positive integers a, b and c can satisfy the equation aⁿ + bⁿ = cⁿ for any integer value of n greater than two.

Given that Andrew Wiles' proof made use of a lot of new mathematics; for example, Ribet's 1986 epsilon conjecture proof and the Taniyama–Shimura conjecture, is it generally still believed that Fermat *did* have a general proof to this conjecture?

Apparently this explains it, but it sounds like BS to me.

Fermat had a proof in the case of fourth powers only, the rest weren't discovered if they were known at the time and I doubt he had the mathematical knowledge to get something anything like Wiles' proof, so I have to say no.

That site made me Why would someone waste their time like that?

It is thought that Fermat assumed that all rings of the form $\mathbb{Z} \lbrack \sqrt{-n} \rbrack$ are unique factorisation domains - I'm told that it's not hard to prove FLT under that assumption. (The assumption is wrong - witness $\mathbb{Z} \lbrack \sqrt{-5} \rbrack$, in which $6 = 2 \times 3 = (1+\sqrt{-5}) \times (1-\sqrt{-5})$.)
