Navigation: Ignore Duplicate Navigations

Chrome now skips duplicate navigations — identical URL navigations initiated in quick succession no longer cancel an ongoing navigation. This saves resources and prevents flicker.

concepts

  1. Duplicate Navigation Demo

    Rapidly click the same navigation link and observe how the browser ignores the duplicate instead of restarting the navigation. A PerformanceObserver tracks navigation counts.

  2. Timing Comparison

    Compare navigation start times when clicking the same URL rapidly vs different URLs. See the dedup logic in action through timing data.
