Accessing external URL from Portable Firefox - Opening the default browser from PFF

Hi All,

I developed an application that uses Portable Firefox browser, and works very well with it. However, I have one problem for now. When I click on a link (hyperlink with extrnal URL) within the content are of my application, the link opens up another instance of Portable Firefox browser window for display.

Since this link is an external URL, how can I have Portable Firefox it up with user's default browser, such as IE?

Can Portable Firefox connect to a URL (external to my application), and open the URL with user's default browser (connection and proxy settings), even in a firewall environment?

I have tried enabling "Auto-Detect Proxy Settings...." in Tool-Option Menu, it didn't work in a Firewall environment.

Does anyone have other ideas on how to accomplish this task?

Thanks,
