Description

Web Application for Firefox Performance Analysis

Capture, Analyze, Share – Accelerate Web Performance

The Firefox Profiler visualizes performance data collected from web browsers. It is specifically designed to ingest profiles generated by the Gecko Profiler, while also supporting any profiler that outputs JSON data. Built with React and Redux, the entire interface operates client‑side within a web application.

Mozilla created this tool to enhance Firefox’s speed and smoothness for millions of users, and to help developers improve performance across the broader web.
