Performance

• Perf+metrics work week this week in MV/SF
• This week's Snappy summary
• Lawrence posted on hacks about Firefox 13 Snappy work.
• Tim landed a fix to avoid setTimeout()s when handling tab clicks in bug 743877, which should significantly improve tab strip responsiveness.
• Incremental GC making progress towards being turned on by default again (bug 750959, bug 752098).
• Wladimir Palant (Adblock Plus fame) wrote a new Suspend background tabs add-on to halt activity in background tabs. This experimental add-on should give a sense of how we can improve lag due to background tabs.
