The first YouTube video was uploaded April 23, 2005. Today you can watch millions of hours of movies, concerts, tv shows and more. Add even more controls to your watching experience with browser extensions Magic Actions Personalized Movie Theater and Enhancer for YouTube.

Magic Actions has a cute user interface that sits in your play bar. You can apply filters and even make the video spin in a circle. But when I installed Enhancer, Magic Actions wouldn’t work. And although Enhancer is much more serious, it had features I liked even better, such as speed controls and a quick volume booster.
