I scratched another itch and created a fix for bug 23460 so that Mozilla will show bookmark URLs in the statusbar when you hover over them in the personal toolbar or bookmark menu. This bug has frustrated me since Netscape 4 broke Netscape 3’s bookmark menu behavior. Even IE5 got this one right. It’s way beyond time that Mozilla did as well.
As mpt requested in the bug, it’s in the statusbar only (although I did leave the personal toolbar tooltips in place). No strange tooltips popping up in a menu to show a redundant URL.
There are a few related bugs that I’d also like to fix: show the URL in the statusbar for the back and forward buttons and menus (bug 88541) and show the URL in the statusbar for items on the Go menu (I don’t think there’s a bug logged for this).
