issue is caused by the threshold value for frame duration used by javaFx before it gets normalized. JavaFx is using threshold value 10 while other browser (Safari, Firefox) is using 50 due to which, value between 10 and 50 don't get normalized and animation runs at faster speed. To fix the issue change frame duration normalization value to <= 50. Safari : https://bugs.webkit.org/show_bug.cgi?id=14413 Firefox : https://bugzilla.mozilla.org/show_bug.cgi?id=386269
