I have read an interesting article about css selector profiling but I haven't found any way how to actually enable this feature. Is there something I am completely missing ?

The CSS Selector Profiler was removed from Chrome 30:

CSS selector matching is now reasonably fast for the absolute majority of common selectors that used to be slow at the time of the profiler implementation. This time is also included into the Timeline "Recalculate Style" event.

As such, I believe the CSS selector profiler is not as useful as it [might have been] used to and can safely be dropped. This will also reduce the fraction of developers trying to micro-optimize already fast selectors.

Just in case anyone still needs the CSS selector profiler, you can find it in the Web Inspector of, I believe, any Webkit-based browser except Safari (Falkon (formerly known as Qupzilla) is just one example).
