It breaks too often and when it does it locks up your browser for an extended period of time.

It struggles on far too many websites and ultimately slows down the majority of website load times. Things once blinked to load and this extension makes them hang.

Sad because it use to work a whole lot better, but I find myself disabling it more and more to the point Im wondering why I even keep it. I also think this is the cause for locking up the entire browser every once in a great while.
