<form name="appForm" method="post" action="NewQ.servlet">
<input value="13" size="2" maxlength="2" name="day">-
<input value="AUG" size="3" maxlength="3" name="month">-
<input value="2004" size="4" maxlength="4" name="year">
</form>
</body>
</html>
Reproducible: Always
Steps to Reproduce:
look at Details
Some web applications need very much that the text input can display all its text .
IE can do it rigthly.
I looked at nsTextControlFrame.cpp and can't figure out why we use
GetAveCharWith(). It seems that IE is using GetMaxCharWidth().( the input width
in IE is always equals a upper-case string's width whild greater than a
lower-case string's width)
Since there is no GetMaxCharWidth() in nsIFontMetrics & nsRenderContext. Maybe
we can simulate one, e.g using char 'X' width.
btw, I didn't try it on Windows version.

Rick, add your comments/discussion to bug 92980 instead.
Also read the various bugs referenced in bug 92980. In my opinion a
discussion for "Unix only" is not very meaningful. This is a complex issue where
finding the right algorithm that works well for *all* platforms and for *all* font
families/sizes is difficult (if not impossible). But I agree with you - the
current algorithm needs to be improved...
