ObscuraGuard od AimiSayo

ObscuraGuard lets you blur or unblur specific elements on any webpage – perfect for hiding private messages, images, or personal details while screen-sharing.
Just right-click on an element to blur it, and the extension remembers your choice across page refreshes and navigation, even on single-page apps (like Instagram).
You can also unblur elements at any time, removing them from the blur list. It’s a simple, lightweight tool for anyone concerned about on-screen privacy.
