I've just upgraded to latest version of Firefox 4 and my Mac is only OSX.10.4.11 and it won't open. How do I downgrade and get old Firefox back. Don't want to lose all my bookmarks. Why was I able to install in the first place. Very frustrated!!

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

You can trash Firefox 4.0 then re-install Firefox 3.6, it will use your existing bookmarks, passwords etc

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
