WP 8 question

I have a windows phone 7.5, the HTC trophy. I really enjoy the os and I am considering getting a windows phone 8 this week when I upgrade. My biggest issue with my current windows phone is how you can not "back" when looking at websites. On android or iOS you can go back to previous sites and go from tab to tab and go back on WP7 you can not. Can anyone with WP8 tell me if you are able to go from tab to tab and be able to look at previous pages?
