Previously Google Chrome used to be my favourite browser. It had instant startup and rapid rendering of web pages. That is until Safari 4 came along. Safari 4 had equally fast startup if not faster but had even faster rendering times. My only annoyance was not being able to block Flash – until now. It turns out that there exists a neat way to block flash – a user defined stylesheet. It’s called adsubtract. To use simply download the stylesheet and add it as a stylesheet in the advanced preferences of Safari. Given that it is CSS it works on any platform which is perfect. Thank God for open innovation and also the individual that came up with it.
