Which exact version of head do you have, and which version(s) of ports? Are you running WITH_NEW_XORG or not?
In any case, I have just built the latest Firefox from ports, with clang 3.3, and I see no issues at all. At least with approximately 10 minutes of browsing, and visiting a varied bunch of sites. I do have it built with debug info, but without cranking down the optimization level to -O0 (which is what bsd.port.mk seems to do, unfortunately).
I will rebuild it again, without any debug info, to see if that makes any difference. I don't think it will, though...
