Removing the 3 pixel gap in Hotmail email for Firefox

A while back I wrote a post about removing the 3 pixel gap in Hotmail. While that provided a solution for IE I’ve since discovered another fix that works in Firefox. It’s the same problem as before; a 3 pixel gap is added beneath images, particular to images inside table cells. The problem seems to stem from the font size settings, obviously this shouldn’t affect a table cell that does not contain text. Chalk it up to yet another That Shouldn’t Make Any Difference But It Does™ This time the fix is to add style="line-height: 50%" to the TD tag. You should then end up with the following:

<td style="line-height: 50%">
	<img src="image.gif" width="300" height="50" alt="" />
