It's great that Firefox finally has this option and I'm surprised that so many people dislike it; it's the single most important feature why Opera is my default browser. I guess the reason why it's confusing to people is that Firefox (just like Sublime) doesn't have that little popup displaying a list of tabs while switching, it would make all the difference in the user experience, and make things clear.
