The object code is:

<a href="javascript:void(window.open('http://www.facebook.com/share.php?u='.concat(encodeURIComponent(location.href)) ));" target="blank" class="sharefb">分享至facebook</a>

If the target="blank" part is deleted, the button works as expected.

They uses location.href , replace with some other URL then works. So it's the problem using blank as the bug https://bugzilla.mozilla.org/show_bug.cgi?id=836567
It's we don't follow the HTML5 spec of javascript: URL as @freesamael comment. Close as duplicate.
