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...
