Disabling image load in JavaXPCom + Getting html document from xulrunner without popping up the widget

Hello,

I need help or some direction for the following questions i have,

1. The guide available from the JavaXPCom document and the other example
using swt browser are popping up the widget and give a visual presence.
Is there a way in which it could be avoided?

2. nsIwebBrowserSetup has the setting to enable or disable image loading.
How can it be used in the JavaXPCom setup?

3. While using SWT browser if i set browser visibility as false, i dont see
the pages getting loaded and i assume that the images dont get pulled in
this scenario.
Is that true? I am looking at reduced bandwidth and load time.

4. Any pointers on loading the extensions in the embedded browser?

5. I have a firefox extension with java connectivity. Can i load this
extension in the JavaXPCom embedded browser?

Thanks for any help you provide.
