I've set up two samples. In the first the overflowing pseudo element part (blue) should be hidden http://codepen.io/rpkoller/pen/buAHm while in the second the overflowing part of the grey div should be hidden. http://codepen.io/rpkoller/pen/DjmsI In both cases if you click with the mouse and keep it clicked and move it to the right the page is scrolled horizontally and the initially hidden overflow is shown. The overflow on the right side for the red pseudo element is hidden properly and impossible to scroll. But on the right webkit is ignoring the overflow-x property completely. The first pen is tested in: Safari: not working Webkit nightly: not working Chrome: not working Opera: not working opera next: not working Firefox: working as expected. 1034639 1 ap 2014-09-11 10:29:41 -0700 I don't see any difference in rendering between a current nightly and Firefox 32. 1034721 2 r.koller 2014-09-11 14:45:14 -0700 (In reply to comment #1) > I don't see any difference in rendering between a current nightly and Firefox 32.

I don't believe there is any remaining compatibility issue.
