How can I download Firefox 4? I can only find no 5. I really need 4 so I can use the Google toolbar. My work depends on it.

I had Firefox 4 on my MAC laptop. I then updated it with Firefox 5 to only find out that Firefox 5 does not support the Google Toolbar. I now need to download Firefox 4 but I can't find it anywhere. How can I download it again?
