download firefox 4

Today, I downloaded firefox 4. It won't install so I threw away the old version. But I found out that my mac os is 10.4.11 so firefox 4 cannot install on it. But I tried to download the old version of firefox but it's not available on your website. Now my bookmarks are gone!

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

There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

Hey Tony, Thank you very much! My bookmarks are back! Thanks God. However, the blue icon of firefox appeared on my desktop every time, I opened FF. And, there is a small screen popping for dragging an icon of FF to an icon of my application folder. I don't need to do that. It's done. How can I removed it?

Thanks!
