safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over two years ago in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

Safari Technology Preview release 60 includes bug fixes and feature improvements for Web Animations, Dark Mode, Web Inspector, Media, CSS, WebRTC, Security, Plug-ins, Intelligent Tracking Prevention, WebDriver, and Accessibility.

The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that’s currently being beta tested by developers.

Of note, Apple says Safari Technology Preview 60 will crash on launch with the first macOS Mojave developer beta. To avoid crashes, users should upgrade to the second or third beta. Also, after updating to release 60, the homepage preference and the Develop menu preference will be lost.

Safari Technology Preview 59, the prior update, introduced support for Intelligent Tracking Prevention 2.0, which prevents social widgets from tracking you without your permission and introduces other tracking prevention updates.

The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.

Apple’s aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.

Does this update fix the YouTube/Netflix glitching in full screen?

Cookie issues are abysmal, sites logging me out with no rhyme or reason, even without closing the browser.
Probably a side effect of Intelligent Tracking Prevention v2.

Also you do know you’re using a preview version of the browser don’t you?

Is there really no upgrade path for the dozens of so extensions I have installed in regular Safari on High Sierra?
There's no "upgrade path" because the Preview is not an upgrade. The Tech Preview, by design, uses independent extensions, cookies, etc. You have to reinstall them.

I wonder why they've removed the Develop menu?

Also, 479 out of 555 on HTML5test. Looks like we've regressed.

Edit: ah, you need to re-enable the Develop menu in Preferences.
