Useful area

As the screens of various devices shrink, the question arises: “Which browser occupies the least useful place?”

5 most popular browsers of the latest version took part in the competition: Firefox 5, IE 9, Chrome 12, Opera 11.5 and Safari 5.
The main and only criterion is the distance from the top of the screen (with the browser maximized) to the beginning of the page itself.

So, immediately proceed to the results of the competition.
First place with a score of 55 px - IE 9;
The second and third with the result of 61 px divided Opera 11.5 and Chrom 12;
Third and 64 px - Firefox 5;
And closes the top five Safari 5 with a score of 80 px.
