Used FF 3.1.6 for years just fine. Downloaded FF4 and when I went to pull it from my applications folder there was no icon, just a square saying FF4. Pulled it to the bar and got a message saying "you cannot use the appliction "firefox" with this version of Mac OS X"

Firefox 4 requires at least OS X 10.5. You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com
