To prevent websites from knowing you've switched tabs, you can use browser extensions that disable the JavaScript `document.visibilitychange` event or modify its behavior. These extensions can prevent websites from detecting when their tab becomes inactive or loses focus. Another strategy is to open sensitive tabs in Incognito or Private browsing mode, limiting the ability of sites to track your focus change through conventional means. However, effectiveness may vary across websites and extensions.

- What are the best browser extensions to prevent tab visibility tracking? Extensions that disable or override the 'document.visibilitychange' event can prevent tab tracking, but availability and effectiveness vary by browser and extension.
