I often find myself opening several new tabs while browsing, and suddenly wanting to go back to a certain page I've seen.

To do this, I need to search for the tab which contains the page that I want to revisit in its history, which is a pain.

Another option is to look through the browser history, but you loose the navigation process; so if you would like to access the page that you visited after this one (that you opened in a new tab), you will have to go through the history again.
