In version 51 now include a quick return to the top of the page without scrolling all the way back up with the mouse wheel. All that's needed is a simple click on the tab of the corresponding page to jump back to the top.
If the side-by-side display of tabs has always been too unmanageable for you will now allow you to display all open or recently closed tabs in a vertical list. There's a new button at the top right of the address bar to check out the lists.
Videos on web pages can now be moved to the so-called pop-out windows, the size of which can be freely adjusted. They'll always be in the foreground, allowing you to watch the video and surf at the same time. To keep the original page of the video from getting lost, there's a “back to tab” button at the top of the video window that will take you straight back to the page. – dpa
