External URL blocked

[Crls]

Not sure if possible but just wondering.

I saw some of the games that people from here have developed and I have notice that when you add an external URL through the flash object and you play the game online, the browser will understand it like it's an emergent window. so in my case firefox will block it.
I saw other flash games, and firefox will take it as a normal link and will open it without problems.

Is there any way to set up this so the browser will interpret that as normal Link?
I tried ( url taget="_blank" ) and open in a new window and seems the same.

Thanks

Anyone?

It seems that is the way that MMF2 is understanding this function,
Is there any other way to add an external URL?
