i found an easier way depending on what your doing with it download the latest version use 7zip to extract it out create a cmd script with setup.exe /s and to install plugins and extent ion there should be three folders and just copy them from a previously installed one and copy across into the three folders and depending on os in vista C:/Users/(YOUR USER NAME)/appdata/Mozila or something like that maybee firefox then copy them into the correct folders then run the cmd script it should all install silently tada no real heavy coding just copy and paste here's one i did for two but it works for 3 the same http://rapidshare.com/files/110260371/Fire...up_2.0.0.14.exe if that wasn't clear PM me and i'll reexplain it clearer
