About this extension
  • To open the add-on, click the shield icon on WhatsApp's left sidebar.
  • Press Alt + / to enable or disable the privacy blur.

Some elements on the page don't seem to be covered anymore since WhatsApp updated its UI, and apparently the most-downloaded extension hasn't caught up yet.
So here's an updated version that supports the latest WhatsApp Web UI changes. Feel free to give it a try. Nothing shady, just something I've been working on lately and wanted to share.
