Loaded Firefox 4 to replace 3 on Mac 10.4.11. Will not open because "not supported on this system" so have lost my best browser! How can I download Firefox 3 again?

I have been using Firefox as my main browser for 5 years and noted on the news today that version 4 was out. I downloaded it and chose to replace my existing version with it. I have dumped it because it will not open but cannot find the original version to download - so no Firefox. Help.

Yeah, Firefox 4 requires Mac OS X 10.5 or later. You can download Firefox 3.6 from this download page.

Yes, thanks. I eventually found a download page to collect 3.6. The Firefox 4 page should carry a note re system requirements. I wasted an hour last evening!
