Details

(Whiteboard: [fxperf:p5])

Each time a new window is opened, three inline stylesheets (<style> elements with child text instead of a separate uri) are parsed: 1. http://searchfox.org/mozilla-central/source/browser/components/customizableui/content/customizeMode.inc.xul#70 2. http://searchfox.org/mozilla-central/source/browser/themes/shared/fxa/sync-illustration.svg 3. Some empty style tag loaded somewhere from browser.xul (I haven't found where this is) On my machine this takes about 2/10 of a millisecond. Investigate whether moving these to separate urls would be faster as the post-parsed sheets would be cached.
