The fire fox icon is crossed and wont open it just says it cannot be launched and marks -10661 I think I have to reinstall the previous version but I cant find it nor I know how to uninstall the firefox I have now.

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

If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
