Header visible in Crome browser but not in Firefox

I need help. Tried for a while now but can't seem to figure this one out.
I was trying to make a smaller header to 150px high. after I edited it and uploaded via Filezila. When viewing the home page after this in Firefox I got a blank as header. When I used Google crome I was able to see the header correctly. Strange. See for yourself. https://www.auroramultimedia.net
Any suggestion Very Welcome. Thanks, Anthony.

There does not seem to be a folder specified where your logo actually resides:

<!--bof-branding display--> <div id="logoWrapper"> <div id="logo"><a href="http://auroramultimedia.net/">Aurora Multi Media</a></div> <div id="taglineWrapper">Timeless values in a changing world</div> </div> <!--eof-branding display-->

shouldn't it be something like

<div id="logo"><img src="includes/templates/YOUR_TEMPLATE/images/logo.gif" alt="Aurora Multi Media Logo" title=" Aurora Multi Media Logo " width="xxx" height="yyy" /></div> <div id="taglineWrapper">

Strange though that it shows in Chrome but not in FF

Thanks for your reply to my post. Should I try to edit it and see what happens?

The logo default size in a new ZC install is > width="192" height="64"

The actual specified logo size would depend on your template, could be specified in your style sheet, or may be specified in one of your files. You will need to find this first - use Admin > Tools > Developers Tool Kit to find the file which determines the allowable size - then change the figures accordingly to match the dims of your logo.

Make sure you BACKUP your files and DB before making any changes

Thanks Frank for your input. Sorry I had to get some sleep as here it was 1:30 am and my eyes starting to hurt after a long day. I'm ging to look into what you suggested. Anthony
