I'm a big fan of the Chrome addon called Concentrate - https://chrome.google.com/webstore/detail/idfmgklhndkcggamadboiaepmohpjhjj https://chrome.google.com/webstore/detail/idfmgklhndkcggamad... .

Of course, you could always switch browsers, but if you're resorting to things like that, I can't help you.
