`driver.get(url)` loads a URL and waits for the whole page to load. `driver.navigate().to(url)` loads a URL and maintains browser history, allowing you to use `back()`, `forward()`, and `refresh()` methods. `navigate().back()` simulates the browser back button, `navigate().forward()` simulates forward, and `navigate().refresh()` reloads the current page.
get() is like typing a URL in the address bar for the first time. navigate().to() is like using the browser's history to revisit a page.
