I have a heavy but html and css compliant web page showing a table in a <div
tag. On load of the page, the div is resized by javascript using
window.innerWidth/Height properties.
A small problem is that during the loading of the page, the size of the page
exceed the window size (look the footer bar) but i doubt this worth the fix.
Then the layer resize nicely but if you scroll it to bottom and switch apps,
then the whole page double height after a few seconds  without touching anything
on the browser!

Reproducible: Always

Steps to Reproduce:
1.Load the page
http://www.cfmekong.com/boats/tt/planning.html?month=5&year=05&nbMonth=12&Search=OK
2.Scroll the layer to bottom
3.Switch apps
4.Switch back and wait 2-3 seconds

Actual Results:  
The page height is doubled, horizontal and vertical scrollbars now appear.

Expected Results:  
Nothing

My screen resolution is panoramic (1680x1050)

I am not seeing this. It is possible that I didn't understand the recipe
fully (and it is certain that as a web user I hate this kind of design).

You might to want to check with a trunk build, as there are probably 
differences between Gecko 1.7.7 and Gecko 1.8 , but I could be on the wrong 
lines.

You are right, the recipe is wrong. The bug is due to a js code setting the
absolute position of a small floating layer. As it is inside the main layer, i
assume i have to do 
 small_layer.style.top=200 + document.getElementById('main_layer').scrollTop;
but this causes the bug to appear. 
Moreover, if i do 
 small_layer.style.top=200;

The floating position is unaffected by the scroll (it's the expected behavior)
of the floating layer (i not sure if it should be, it's the case with ie trough)

I don't know if i'm really clear here ;)
To put it more simple : Does the (absolute) position of a floating layer depend
on the outer layer or on the page itself ?
If it's on the page, then it's another ie bug, if it's on the layer, then i
think it's a firefox bug ;)
