Apple has released Safari 10.0 for OS X 10.10.5 Yosemite and 10.11.6 El Capitan (it’s included with macOS 10.12 Sierra). While it doesn’t include some of the features available in Sierra (such as Picture-in-Picture), Safari now defaults to displaying HTML 5 video when available, enhances security by running plug-ins only on authorized Web sites, improves formatting in Reader view, and remembers the zoom level for each Web site you visit. The update also addresses several security issues, including the usual memory corruption issues in WebKit, validation issues in Safari Reader, and address bar spoofing in Safari Tabs — all of which could compromise user information if visiting a
maliciously crafted Web site. Safari 10.0 is available only via Software Update. (Free, release notes, 10.10+)
Is there any way to change that behavior? While html5 video is great, there is no easy and universal way to prevent websites from abusing it. Like CNN that auto-plays videos. At least with flash video, I can disable auto-play by using ClickToFlash. Or if there is a universal way to prevent auto-play of html5 video, that would be better, and more future-proof.
If you use Safari Stand, do not update to Safari 10; otherwise, Safari Stand will break, and the developer, Hetima, hasn't said if or when they'll be able to fix it. I found this out the hard way, and it is not easy to roll back to an earlier version of Safari, since it's now basically integrated with macOS. I restored my entire system from a cloned backup. If there's an easier method, I'd love to hear it.
Also kills click to plugin and every other video-downloading plugin I can find, As I use this a lot for gathering materials to teach with, it's a real bummer.
I have a plugin for a video player (Vitec EZ TV) that isn't working in Safari 10. I can turn the plugin on in the Security settings for the site, but it still doesn't work. Is there a way to back security down to Safari 9 levels?
