User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:18.0) Gecko/20100101 Firefox/18.0
Build ID: 20130116073211
Steps to reproduce:
Wrote this code in an HTML page (as clean and small as possible, all CSS inlined):
<!DOCTYPE html>
<html lang="it">
<head>
<title>Whoa!</title>
</head>
<body>
<div style="background:#777;">
<div style="float:left;">button</div>
<div style="clear:both;"></div>
</div>
<div style="margin:100px 0 0 0;border:1px solid red;">What the F?</div>
</body>
</html>
Firefox (18.0.1 OSX) adds the (100px) margin BOTH to the bottom DIV, and to the TOP div!
Actual results:
Firefox (18.0.1) adds the (100px) margin BOTH to the bottom DIV, and to the TOP div! So the top (background:#777) DIV is not on top of page but in the middle of it. In other words a margin is applied to a DIV that has no margin whatever.
Expected results:
The top (background:#777) DIV should stay on top of page, while the bottom DIV has a 100px margin on top
- removing the float on the button makes the wrong margin disappear
- removing the clearing div makes the wrong margin disappear although top deiv becames thin (as expected)
- changing the margin:100px to a padding makes the wrong margin disappear
- setting a border:1px solid red to the top div makes the wrong margin disappear (?!?!)

Based on the description of the bug envelope in comment 1, I think this _is_ bug 451791, not just a relative.
