Latest Firefox rolls out Enhanced Tracking Protection 2.0
Off topic, but every time I see an article like this I load up Firefox and try it out to see how it has progressed.  I inevitably stop using it, and this time I decided to introspect and see why.  It turns out that it's mouse wheel scrolling doesn't feel as snappy as other browsers, and for some reason it bothers me a lot.  I'm going to try changing the scroll wheel settings and see if I can stick with it.
