Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; de; rv:1.9.2a1pre) Gecko/20090120 Minefield/3.2a1pre ID:20090120020322 and back to FF2.0.0.x All pre-filled textfields under the preferences dialog offer the undo feature. Pressing Ctrl/Cmd+Z resets them to an empty value or 0. Steps: 1. Open preferences dialog 2. Goto Main, focus homepage textfield, and press Ctrl/Cmd+Z 3. Goto Privacy, focus the date textfield, and press Ctrl/Cmd+Z With step 2 and 3 you will notice that the current value is resetted. For a correct behavior the undo action should not be available, when no user-action has taken place.
I'm going through a deleting frenzy with my email, and am discovering long forgotten bugmails - and long forgotten bugs. Henrik, is this still a problem? I don't see it with your STR. I'd hazard a guess that one of the various undo/textbox.xml patches from mid 2009 fixed this long ago.
No works for me too in a current Aurora build. Closing as WFM.
