Many Asian languages are written in top to bottom text direction, but they are forced to be displayed in horizontal direction. It would be nice if Firefox could support this "top to bottom" feature. Note that IE already supports this since 5.5: http://msdn2.microsoft.com/en-us/library/bb250415.aspx It is a part of CSS3: http://www.w3.org/TR/2002/WD-css3-text-20020515/#Progression So, if FF could implement partial support of CSS3 for this, that would be great.
