ramiro showed this to me yesterday: bring up viewer, toggle "Debug | Style | Widget Render Mode " from Gtk to Native, and a preferences.js file will get created. I talked to mcmullen, and he thinks the problem is that we aren't initializing prefs the right way. (In the new world, we need to get the prefs service, etc.) I'll need to do the same thing in the viewer main as we do in nsAppRunner.cpp's main.

marking for m7. m6 is packed for me.

This is all fixed already. Marking it so.

Actually, what happens now is that a file will be created in the cwd called "default_prefs.js". The reason this is not really using the right location for the prefs file is that nsIFileLocator is not a standalone component (see bug #5571) - it lives in appshell dll. Therefore, when code in viewer tries to get the nsIFileLocator service, it fails, and falls back on the default. Anyway, preferences in viewer are now at least working (using the cwd location), and so this bug can be closed.

thanks for fixing this.

Moving all libPref component bugs to new Preferences: Backend component. libPref component will be deleted.
