I have a home page where I use two IFRAMEs.
Since several weeks, one Iframe is not rendered rightly, it falls down the page
without any reason.

You can check these two attachments, made with latest 1.4rc2 and previous Camino
0.7.

Attachment: This is a snapshot of the homepage correctly rendered by Camino 0.7

You see the iFrame indicated by the arrow, a long list of titles and dates.

Attachment: This is a snapshot from Mozilla 1.4rc2 - the iFrame is missing

If you go at http://www.astrologiadinamica.it you see the iFrame put for below
its right position.

this bug is here since a few weeks, probably the new XUL engine has some
wrongsetting.

This problem is also with Mozilla Firebird.

Don't know about windows.

We fixed a bug in float rendering since 1.3.  The bug was a violation of rule #5
at http://www.w3.org/TR/CSS2/visuren.html#float-position

In particular, you have a right-floater (iframe with id "testiBase").  Then you
have another right-floater (div with id "Postfazione").  The left-floater in
question (iframe with id "annoPolitica") comes after them in the DOM, so its top
may not be above the top of the "Postfazione" div.  Which is in fact exactly
what you are seeing in our rendering.

So the layout you are now seeing is in fact required by the definition of "float".

Thanks for the time you took to explain this, I will rewrite the page just now.
Mozilla beats them all!!!
