When firefox starts it seems to access /usr/tmp:
Sep 14 09:35:49 fedora kernel: audit(1095179749.095:0): avc: denied
{ read } for pid=4728 exe=/usr/lib/firefox-0.9.3/firefox-bin name=tmp
dev=hda2 ino=4112460 scontext=user_u:user_r:user_mozilla_t
tcontext=system_u:object_r:tmp_t tclass=lnk_file
donaudit, e.g.?
dontaudit $1_mozilla_t tmp_t:lnk_file read;
