    Firefox Profiler — Web app for Firefox performance analysis

    • Please file bugs with performance profiles to help investigate things. Firefox devs need good info, and it's not always easy to get it. It could be anything from some optimizations not being implemented yet, to garbage collection taking place at bad times, to sites simply running different code on Firefox (yes, really, I see that in my webcompat work).
