YSK websites can see what other tabs you have open through a tracking technique called canvas fingerprinting
Why YSK: Some sites use your browser's canvas feature to create a unique fingerprint of your device based on how it renders images, and this can be matched against known profiles to guess what other sites you're logged into or have open. You can block this by using privacy extensions like CanvasBlocker or enabling anti-fingerprinting settings in browsers like Firefox or Brave.
