Here's my checklist.  This works on 6.2-Release and 6.2-Stable as of 
16 Jan 2007 with Firefox 2.0.0.1:

Install the dlsym patch:

Note: a new version of rtld.c came out in stable on 16 Jan 2007.  If you 
don't run 6-Stable, fetch the patch file like this:

# cd /usr/src/libexec/rtld-elf/
# fetch http://people.FreeBSD.org/~nork/rtld_dlsym_hack.diff

Here's an updated patch file I made for rtld.c v 1.106.2.4:
