I checked this out and cannot see the problem, did you fix it?
I see it as in Benoit's screenshot. What version of FF are you using?
Benoit, I see the exact bug in forms2.js that's causing this, but I haven't found a workaround yet (aside from replacing the whole script with an updated version, which is obviously not recommended).

This will compensate for a bug in the Marketo modal rendering where it miscalculates the height as < 0.
