I was browsing the Mozilla site with a friend for an OS 9 build of Mozilla and looked at the Phoenix project just in case they made an OS 9 version Lo and behold, we found someone who made a build of Phoenix for OS X! No, it is not an official version and is not a mozdev project, but it still works. And actually, it works pretty well. I am posting from it right now. Here is the link from the guy who made the build http://www.kmgerich.com/misc.html Belive it or not, it actually seems faster than my latest Chimera nightly. It is from the latest version of Phoenix which is 0.4. I am fairly impressed for something that was just a quick port. Enjoy! Here is a screen shot of it running on my machine.
