The Firefox Profiler is a web-based tool for visualizing performance data from web browsers, designed primarily to consume profiles from the Gecko Profiler but capable of handling data from any profiler outputting JSON. Built with React and Redux, it runs entirely client-side and is maintained by Mozilla to help optimize Firefox and improve web performance across the internet. The project is open-source, accessible, and welcomes contributions from developers interested in browser performance analysis.
