I need to resize many iframes beacase use AJAX in all of the inside html pages.

If Ajax don´t return rows i don´t need to resize but many time Ajax return many informatión and need to resize de Iframe that contain it.

In this situatión the program can call 2 or 3 times a JS function that calculate the page Height and set it to the iframe that contain it.

Firefox version < 3.5 works perfectly but with >= 3.5 fail :-/

Its curious to see if i do an alert ('hello') before every change of height properti of the iframe the iframe change !!!! :-).

We things the problem is new javascript engeniere is caching the property but not sure.

Thanks in advance

Confirmed on Windows Vista, latest trunk. Regression range appears to be: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=2e7f03bc1820&tochange=07afef6cd29c

A *minimal* testcase would be very useful here.

...because I couldn't write one immediately.
http://mozilla.pettay.fi/moztests/iframe_height.html works fine here.
It tests both .height and setAttribute('height', ...)

Which JS function is that? 
Like Olli said, if you could come up with a minimal testcase that shows the problem, that would be great.

With current trunk build I get as value "350px" for the relevant iframe and "387" for Firefox3.0.x as the height value.
