If I follow the instructions that someone posted in the response here (about:config):http://www.lifespy.com/2008/firefox-quick-...ss-bar-history/
I can stop the links from appearing in the drop-down. However, that also stops it from remembering new sites. If I change the number back to a positive, all the old sites appear again. This is not how it works with IE, where once the history is deleted, they don't appear, yet the new sites do appear.
So, is it possible to delete the old sites from appearing yet have new ones remembered?
