In IE the last line "You must log in to Submit this form" is highlighted in the corresponding color. But in Firefox this highlighting disappears. Please tell me how to have this highlighting in Firefox as well.
I think that it should work. In Firefox Options, check that the option "Contents/Fonts and Colors/Color Settings/Use web page settings in priority" is turned on. (I don't have an English Firefox, so I can't tell the right label names)
