Looks like it works in Internet Explorer because the object-tag is set up correctly, but it doesn't work in firefox or chrome because the src attribute of the embed-tag doesn't contain the right url to the swf-file.
You should use the same url in the embed-tag as in the object-tag.
So, on the page you posted in post #3, you would need to change the embed-tag like this:
Find:
Code:
<embed id="player1" width="600" height="400" src="rotateTool.swf" flashvars="path=deuter" allowfullscreen="true" allowscriptaccess="always" name="player1" scale="noScale" salign="lt">
Replace with:
Code:
<embed id="player1" width="600" height="400" src="https://www.mehost.co.uk/tutorials/Subdomains.swf" flashvars="path=deuter" allowfullscreen="true" allowscriptaccess="always" name="player1" scale="noScale" salign="lt">
I have tested the code and it looks like it works correctly.
