Enabling sending referrers (again…)

I supose this problem has been already treated in this forum, but I’ve still have found no real solution. I use Mozilla Firefox 1.5 under Debian GNU/Linux, and NO WAY I’ve got ‘sending referrer’ to work. I’ve followed the steps on the help page, but nothing… And It feeds me up, because I can’t delete posts, add links, or even change the default theme! I hope someone helps me…thanks anyway.
See you!
