Changing the popupshowing listeners to contextmenu is necessary because one of them hides the view which calls hidePopover on the urlbar, preventing the context menu from showing because of bug 2037468. Using a contextmenu listener instead calls hidePopover before the contextmenu starts showing, avoiding the bug. Differential Revision: https://phabricator.services.mozilla.com/D299174
