Comment 4 for bug 109440

You can't really see what's going on in a single screenshot, but hopefully this attachment makes the situation clear. For a right click in the tab bar, the bookmarks bar, the tool bar, or the menu bar the context menu starting with "Back" always appears above the context menu I would contextually expect (i.e. the context menu for the tab, the bookmark menu, the toolbar menu, the textbox menu with Undo/Copy/etc for the address bar).

Interestingly, if I hold the right mouse button down and move the mouse the incorrect menu does not appear.
