Seems like the Performance Tools is now on par with Chrome, unless I'm missing something. These tools are sorely needed for web developers, Nik Molnar's talk[0]

Seems like the Performance Tools is now on par with Chrome, unless I'm missing something. These tools are sorely needed for web developers, Nik Molnar's talk[0] on web performance is a great intro on how to use these in real world scenarios.

Memory profiling is a big missing piece, but it's in Nightly right now, and should show up in DevEdition 41 or 42 :)

  Will this at all help to help diagnose and maybe even fix why FF eats so much memory? I keep getting out of memory errors in windows and see FF eating tons of RAM & Virtual, and have no idea which is causing the errors or how to fix it.

    That sounds very unusual. Have you got any add ons installed? I suggest trying a clean profile to see if that helps. Unless you have lots of content open that inherently uses a lot of memory, or something.

      Nope, extensions are fine (as per about:addons-memory) From sysinternals process explorer I see working set 1.6GB and Virtual Size 2.6GB with ~200 tabs open. Don't understand why the virtual is so big.
