I dragged it into applications and then it wouldn't open. a dialog box appeared "this application is not supported by the architecture. have an Imac 10.5.8

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party build that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
