I tried to update my browser to Firefox 4.0 and now the browser does not work. How can I go back to the prior version? I was looking for a way to reactivate it or download it again.

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
