When surfing the web using Safari on older versions of iOS, the back button, the new tab button and the bookmark button were always on the screen (no matter where you were on a particular page). That’s changed in iOS7. The move saves some real estate on the screen, but it’s not immediately apparent how to pull up that actions bar after you’ve scrolled partway down a page. Here’s how to launch a new tab or hit the back button in iOS7 while in the middle of a page or browsing:
1) Tap the web address at the top of the screen:
2) That tap expands the URL bar, and the actions bar will appear at the bottom of the screen (which allows you to open a new tab, hit the back button or bookmark a page):
This works for iPhones, iPads, iPods and anything else running iOS7.
Bonus tip: if you just want to go back, you can also do that on any web page in iOS7 by swiping from the left side of your screen to the right.
