Breadcrumbs in Web Navigation. On breadcrumbs vs. the back button, one user said: “It’s safer to push ‘back’ because I know what I’ve seen. If I push this [breadcrumb link] I don’t know if I’m going to get what I got before. I don’t want to waste any time.” Moral: unless it’s a single‐page application, do not break the back button in your web app.
