I [googled](https://www.google.com.au/webhp?sourceid=chrome-instant&ie=UTF-8&ion=1#hl=en&safe=off&sclient=psy-ab&q=dom+mutation+observers+support&oq=dom+mutation+observers+support&aq=f&aqi=&aql=&gs_l=hp.3...69.32879.0.32981.37.32.2.0.0.0.326.6714.2-27j3.30.0...0.0.xsxdy9m5QyQ&pbx=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&fp=6fe1c4b9df5a02ef&ion=1&biw=1440&bih=712) but couldn't find an answer.

Is there a cross-browser compatibility matrix available for this feature?

In case anybody wants to know the answer, here it is: [Mutation Observers vs Mutation Events/Browser Availability](http://code.google.com/p/mutation-summary/wiki/DOMMutationObservers#Browser_Availability).
