Yay Rated 5 out of 5 stars
I'm currently switching back to firefox after using chrome for a year. I installed the addon from the mozilla site and was having slow startup times and ugly stuttering while scrolling. After reading that I should install directly from their site instead. I just installed that one over the one that was already installed and my startup time was back from 5 seconds to 2.3 seconds and no horrible stuttering while scrolling!
