I keep getting messages to upgrade to FireFox 4, and it will not open on my Mac OSX 10.4.11. I get messages that the 3.6.17 version is not secure.

Firefox 3.6.x versions are still updated with security patches (Firefox 3.6.18 is due in about two weeks).

You are unfortunately out of luck with an Intel Mac and OS X 10.4.11.
There is a compatible version from for a PowerPC Mac, but no alternative for an Intel Mac.
