Open the html5test site in Safari 12.1.1. Before you concern yourself with the displayed score out of 555 possible points, read the bottom content About HTML5TEST — so you understand what it does, or does not do.


Open Firefox 67.0.4 and compare its HTML5 support to Safari 12.1.1. There is more here with what is/is not supported, and if it really matters to your particular need — then the top score differences.

Thank you. Revealing information. It appears that Chrome and Firefox score higher overall. Biggest difference appears to be in the Forms test where Apple and Firefox do not do well, but Apple outscores both in Video. I am going to move forward with trying Safari alongside Chrome and see if I see any additions as I work up the class assignments. Thanks again.
