I tried using : id = npnfuncs->getstringidentifier("document"); in GtkLauncher

Although this time there was no segmentation fault, but the string "Hello from wcfplugin......" did not print either.
It seems "func" is not found.

You should also check the return value of NPN functions.

It's not correct. It's non standard.

As you can see here: https://developer.mozilla.org/en/DOM/window.content
it is not part of any W3C specification.

Available window object properties are:

I think you should try window.document
