so lets quote it a bit:
updated download links:You will first need to download Gecko plugin API and Firefox source code. Download Gecko SDK and extract to \yourroot\gecko-sdk\.
Download Firefox source code from here, extract to \yourroot\mozilla.
Then we start from a basic plugin sample. Go to the folder: yourroot\mozilla\modules\plugin\tools\sdk\samples\basic\windows.
Here's a little trick, we need to run unix2dos on npbasic.dsp and npbasic.dsw under this folder. Then we open and cover the project by Visual C++ Express, we will be successful now. From project properties, change the Additional include directories to yourroot\gecko-sdk\include; yourroot\mozilla\modules\plugin\tools\sdk\samples\include. Try to build now, if successful, we continue...
NOTE: well i prefer just open on wordpad, press enter and save it

ftp://ftp.mozilla.org/pub/mozilla.org/f ... ce.tar.bz2 (this is for 3.0, doh =P)
ok so lets make some changes to the plugin.cpp file (this is heavily based on embbeded aplication on playpen)
you can download the code http://gp.leveldesign.com.br/plugin.rar (i havent put basic.rc because mine is slightly modified - use the one that comes with the example. Also make sure you correct the library and include paths on project seetings to your ogre folder)

Test the plugin
Copy npbasic.dll to C:\Program Files\Mozilla Firefox\plugins\ or yourfolder\Mozilla Firefox\plugins\.
From the folder yourroot\mozilla\modules\plugin\tools\sdk\samples\basic\, you will find test.html, double click
Another way to test the plugin
If we open a file of the type that a plugin is registered, then the plugin will be triggered. Open basic.rc with a text editor, find the string "FileExtents" and change the value to whatever you want. I left it as .bic, the default value.
beatiful
PROBLEMS:
1)when i close the firefox tab or window, that .dll isnt unloaded, i still dunno why, you will have to close it from task bar probably
2)Having problems to link with OIS.
3) if you have problem compiling:
in the header file npplat.h
move the block:
#ifdef XP_WIN
#include "windows.h"
#endif //XP_WIN
to the top, not the exact top, but comes before all the other includes.
maybe some one with more knowledge on npapi can help solve these problems
