"Minimum font size" dropdown in Options->Content->Fonts&Colors->Advanced is not correcly displayed on Gnome when there isn't a selected value.

Which build of Firefox are you using???

Taken a couple of hours ago from latest-trunk: the problem is present both on en-US and localized builds (it-Italian) Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b4pre) Gecko/2008022304 Minefield/3.0b4pre

I noticed this too since a few days (Windows XP). Regression window is http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1200370500&maxdate=1200372779 Could be bug 408940 I think.

On Mac Os X (Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; it; rv:1.9b4pre) Gecko/2008022304 Minefield/3.0b4pre) I don't see the problem: the dropdown has no value but it's correctly displayed (empty but with the right dimension)

This is a dup of bug 414247, which was marked as duplicate of bug 414089. We have actually 2 different issues here: - "None" should be selected (this is covered by bug 414089) - A menuitem without selected value should have the same height as menuitem with a value. This issue is very visible on Linux (see the attached screenshot) but also exists on Mac and Windows (but there is only a difference of 1 or 2 pixels on these OSes).

Thanks Florian, you're right: this is a duplicate of bug 414247 ;-)
