Your browser menu should now contain the ‘More tools > Browser Toolbox’ option. In the settings, scroll down to the bottom right (under the ‘Advanced settings’) and check the last two options: Enable browser chrome and add-on debugging toolboxes To do this click on main menu icon, then ‘More Tools > Web Developer Tools’ ( Ctrl-Shift-I), then, in the Developer Tools frame (or window) click the three dots menu icon (top right) and select ‘Settings’. The Browser Toolbox is disabled by default, so, for the above paragraph to work must first be enabled. The Browser Toolbox window can be opened through the browser main menu (the little hamburger icon, rightmost in the URL bar of the browser) ‘More tools > Browser Toolbox’ (or Ctrl-Shift-Alt-I). NOTE: If your browser menu does not have a ‘More tools > Browser Toolbox’ option, then the Browser Toolbox is disabled, and cannot be causing the sticky popup behavior. If unchecked the popup/context menu will close if you click outside it). (If checked you get sticky popups/context menus. To disable this setting, go to the Browser Toolbox window (the window title is ‘Developer Tools – Debugging’), then, in the upper right-hand corner, press open the three-dots menu, and uncheck ‘Disable Popup Auto-Hide’. (This setting is only in effect when the Browser Toolbox window is open.)

IF your browser extension popups (and right-click context menus, bookmark menu etc.) persist and refuse to go away unless you press Esc AND you have the ’Browser Toolbox’ window open-then you have probably left the ‘Disable Popup Auto-Hide’ option enabled.
