 Yosemite. Is there a way I can find out? Computed CSS does not seem to
 provide the answer (it just lists "Helvetica Neue DeskInterface").

 For Firefox 38.0, I often use the two Firefox addons, DOM Inspector and
 Element Inspector. Then you can shift+right-click on the button and it
 opens a window showing information about the button. Then under the
 menubar, choose View > Object Viewer > Used Font Faces.

 > It is a fairly widespread problem, although some buttons look OK; maybe
 those portions of the UI use a fixed height in CSS or XUL.

 > Is there any chance that text is being rendered using font A but metrics
 (e.g., height) are being derived from font B? The behavior Yawning saw in
 #17550 makes me suspicious - even if the wrong font is used, I would not
 expect the height to be such a mismatch for the rendered text.

 That's a very good point. Yawning's bug is especially weird, because the
 element sizes go so badly wrong.
