Your scrolling through the web and you decide to go back to a previous page so you hit the back button. But that's not the page you want so you click it, again and again, to get back where you wanted. There is a quicker way, and it seems to work with all browsers. Just hold down on the back button and you'll get a pop-down menu of the previous pages you came from. Just click on the one you want. This also works for the forward button.
