I don't know how it's done, just that every single other website I go to doesn't put me back at the top when I refresh. I've been using Firefox for years now and I can't think of any time I've had this ever happen to me on another site.
Try:
http://community.livejournal.com/wow_ladies/ and scroll partway down, you should just stay where you're at unless you do a hard refresh.
I keep the "Unread Threads" open in a tab during the day and refresh to see if anythings new and every time I have to scroll down. It's livable, but really annoying after awhile.
