See Previous Pages In Firefox 4

Firefox 3 displayed a small arrow next to the previous page and next page buttons in the main Firefox toolbar that listed previously accessed web pages and allowed you to choose which one you wanted to go back to. That little arrow is no longer present in Firefox 4. However, that doesn’t mean the functionality is gone. It’s still there, but the interface of Firefox has been cleaned up and streamlined.
Just because you can’t see the page history doesn’t mean it isn’t just as simple to access it though. Now, instead of clicking that mini arrow next to the big arrow, you can just right-click the big arrow and you will still see, and be able to click on, previously viewed pages. This is just one more change in the latest version of the Mozilla browser that will take a bit of getting used to.
