This is a potential bug that was present in the later Betas and now the public release. It's happened to me on a few websites where you click the Reader button and it opens a completely different webpage to that you were reading. As an example, this webpage sports story; Selected test news story example Is changing to this story for me when I enter Reader mode; Story shown when Reader mode engaged Could someone else please try this for me? Just click on the original link and then select Reader mode and confirm that it changes to a different webpage. Cheers. Oh I'm on a 4S with iOS 7 GM browsing in Private Mode. EDIT: it's even worse than I thought as it appears to be changing to random webpages. I closed the page and reopened it with the forum link above and it then changed to a story about boxer David Haye.
