Edge: State of web developer tools
summary
Microsoft Edge adds a built-in JSON Viewer, a customizable Focus Mode for the DevTools UI, and exportable enhanced traces (.devtools) that preserve source files, console logs, and DOM snapshots for reproducible debugging. Performance tooling includes Selector Stats (requires advanced rendering instrumentation) to identify slow CSS selectors, and source-map integration in Edge 111/113/114 plus Azure Artifacts symbol server support to map minified code and heap snapshots back to original sources. A Crash Analyzer experiment applies source maps to collected stack traces. Metrics note: 40% of users abandon sites after 3s.
