For those who had used Opera before, you should know what this means. "One of my, if not, the favorite feature of Opera was instant Back and Forward. Now I can go on one website, follow thru 5 or so links on the same site/server. Some pages come up instantly while others take 4 seconds as I click to go back and forth. Its always the same page that is either slow or instant." To bring back forward and back speed, change History Navigation Mode = 3 in opera:config and remember to save. Restart Opera and viola !
