...Am I the only one who, for some fonts, has issues with the overlapping section of the "A" character in Firefox?

Recursive isn't the only font where this happens, but I did notice it for Recursive. I've also observed this on more than one computer, so it's not just my machine!

Nope, you are not the only one! That is an issue of the font renderer using an “even-odd rule” in vector rendering.

What is your OS & OS version? This has generally gotten better over the past couple of years.

You can also use the static fonts, however, which don’t have vector overlaps, and Will therefore avoid this issue. In fact, it you were working on print design, it would probably still be better to use static fonts at this point.

Maybe it helps to set the OVERLAP_* flags as described in the glyf table spec?
