Thanks Dave for the zipper with must have stuff. Probably I forgot one, but I did copy all to the directory eCS\dll. The nss stuff was already in the right place, same date same time. No nix directory stuff. Next you have to re-install all what you had added. First get the browser in my language. Next get the fonts right, tabpage kicked out in order to get my page space back. Have to install or renew the mm stuff, but a youtube film did play, only it stutters. Seems to be a problem in FF, not in porting. And finally its sees the world instead of only my computer system. All in all, its getting worse with FF if your mindset is somewhat different, your native is not English and your screen is still modest instead of some kind of digital wallpaper.
