Hello, I used to make great use of this tool: http://www.wincert.net/forum/topic/3637-tool-ffam-v10211/ to create silent costumized addons for Firefox, with costumized extensions, flash player/shockwave and more plugins, about:config configurations, and all prefs.js alterations I had done on an installed copy in XP. However, the tool doesn't work anymore, and I would like to learn how to do it manually. I have read many tutorials that use different approaches, but don't include all the customizations I used to be able to do before: http://mike.kaply.com/2010/06/18/customizing-the-firefox-installer-on-windows/ I am able to create addons for less complex programs reading tutorials from Ricktendo: http://www.wincert.net/forum/topic/4659-video-how-to-make-silent-switch-installers/ But I can't go beyond using the /ms switch using those methods. Any hints, or help would be much appreciated!
