How to close firefox in nsis?

[Anders]

well, the message is WM_SYSCOMMAND + SC_CLOSE so it should work, but you could try WM_CLOSE as well, and if both fail, bring out the big hammer and call DestroyWindow with the system plugin...

(But why not just ask the user to close firefox? They might want to save bookmarks etc)

I tried both WM_SYSCOMMAND + SC_CLOSE and WM_CLOSE in Firefox 4. They don't work. If you like, you can try them in Firefox 4 too. It won't take much time if you already tried it in Firefox 3.6. They just simply don't work.
Could you give me an example how to use DestroyWindow with the system plugin? Thanks a lot.
