Waterfall analysis, throttling, and blocking requests to debug performance.
### Throttling
Simulate "Slow 3G". Does your app show a skeleton loader or a white screen?
### Block Request
Right-click an analytics script -> "Block Request URL".
Does your site load 2x faster? Now you know the culprit.
### Screenshots
Enable "Capture Screenshots" to see exactly what the user sees at each millisecond of the loading timeline.
