Firefox blocking pop up window

Hi,

I have a Flash movie that loads an html file with a link that should open a new window when clicked. The problem is that Firefox blocks the new window from opening, and I don’t know how to solve it. Unfortunately, I have no access to the HTML page where the Flash will be included, so I couldn’t use Javascript in that HTML page.

This is the code in the HTML file that is loaded into the Flash movie:
<p>This is the company that makes Photoshop:<a href=“http://www.adobe.com” target="_blank">Adobe</a></p>

Is there anything I can do to make it work?

Thanks for your help
