Using FF 3.6.8. Upgraded from FF2 a few months ago when I found "Old Manage Bookmarks" extension that allows me to see all bookmarks and folders at various tree levels in one window. But since upgrading, I cannot add a bookmark for a current webpage by any method other than create new bookmark, copy and paste URL. Certainly no one-click method. Have disabled my two bm extensions (one noted above and Add BM Here), and then all extensions, to see if problem vanishes. It stays. On Windows XP SP3.
