* This week's [http://blog.mozilla.org/tglek/2012/07/09/snappy-update-for-week-of-july-5th/ Snappy summary] | |||
* Jared Wein discovered that about:home was surprisingly expensive to load. He sped up the page by an estimated 30% in {{bug|765411}}. | |||
* Alex Crichton added ability to profile JS in {{bug|761261}}. | |||
** Benoit Girard is adding labels to the profiler to expose JS profiling info in {{bug|707308}}. Same functionality will also allow us to add URLs to the stacks. This means that in addition to seeing what Firefox is busy with, the profiler will now provide context on what caused the processing (screenshot). This is huge. Benoit also improved profiler timing data in {{bug|769989}}. | |||
* Nicholas Chaim updated his addon to track system IO usage while starting Firefox. It's now on [https://addons.mozilla.org/en-US/firefox/addon/slow-startup-logging/ AMO] and automatically uploads results. If you suffer from slow Firefox startups, please help us identify common IO hogs by installing his addon. Please encourage friends with slow startups to do the same. | |||
