Block view-source shortcuts (Ctrl/⌘+U, F12, Ctrl+Shift+I/J/C)
Intercepts the keyboard shortcuts that open the page source and the browser’s developer tools.
This is best-effort only. Browsers do not let a page block their own menus, so a visitor can still open the source from the browser menu or with a view-source: address. Treat it as a speed bump for casual visitors, not a lock.
Show the message if DevTools appears to be open
Shows your protection message when the developer tools seem to be open. Detection is based on an unusually large gap between the window and the page size, which often — but not always — means DevTools is docked open. It can misfire on some window managers, or when the browser window is resized in an unusual way.
The free plugin only shows the message. With PRO you can instead blur the page or redirect the visitor — see DevTools reaction.
