Your question is actually impossible to answer, but I avoided sending it back to the admins because the reason it is impossible to answer may help you understand how that button works. I tested it myself, by visiting sites A, B, C, and D in that order, clicked the back button twice, visited page E, but then I could only click the back button two times before I simply ended up back at site A, and the list was cleared. If I had simply noted that and visited pages F, G, and H, clicked back once, and visited page I, the sites in the list would have been (from bottom to top) A, F, G, I. So, a browser basically keeps a linked list of sites, with the most recently-visited site on top. This INCLUDES the site you're currently visiting. Clicking the back button erases the top element in the list, and of course sends you back one page in the process. Now, I say that it includes the site you're currently viewing because the browser needs to hold that information in case the user visits another site. The "Go" button simply does not display the top item in the list, which makes it look the way one would expect it to look. Thanks, Justin Miller
