I know for a fact that I don't particularly care for the layout or any of the new features. A newer version of firefox is on the desktop and while it's alright, one thing bothers me. With the exact same settings, the other firefox does not completely block all pop-ups on the browser like my current version. I know that my own version is by now "unstable" but other than that, why should I upgrade to a version I dislike for just that one reason?
