Why so small in Firefox ?

Hi,

I can't consider why my site becomes so small when I view it with Firefox browser ? :o

I set width=100% height=100% both object and embed properties.

But it doesn't work. :(

Thank you so much for your kind review.

Does it only work with width="768" height="576" px in Firefox ?

Doesn't Firefox understand % ?

Can we have a link to the page in question please?

Yes FF understands percentages but the html and body in CSS need to be set to 100% height.
<style type="text/css">
html, body {
height:100%;
margin:0;
padding:0;
}
</style>
Add that in between your head tags. Note the object will be 100% width and height of its container. So if its just by itself on the page then it should be fine, if its in a div, then you will have to set that div to 100% height as well.
