Apple Releases Safari Technology Preview 110 With Bug Fixes and Performance Improvements

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

‌Safari Technology Preview‌ release 110 includes bug fixes and performance improvements for WebRTC, Web Authentication, Web Animations, Web API, Media, CSS, Layout, Rendering, Accessibility, JavaScript, Storage Access API, Text Manipulation, Security, and Web Inspector.

The current ‌Safari Technology Preview‌ release is the built on the new Safari 14 update included in macOS Big Sur with support for Safari Web Extensions imported from other browsers, tab previews, password breach notifications, web authentication with Touch ID, and more.

The new ‌Safari Technology Preview‌ update is available for macOS Catalina and macOS Big Sur, the newest version of the Mac operating system that's set to be released this fall.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in System Preferences 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.

I use the regular Safari and the Tech Preview side-by-side for different sites and barely notice a difference. Overall, Safari remains my favourite browser.


They have fixed that annoying bug that caused it to crash whenever you opened a new window. Even though I knew about it I still did it 10 times a day out of habit.
Zero crashes here. Maybe something related to your settings? Do you have it open a particular page? Do you have it remember opened tabs? I don't have any of that... just opens to a blank page, not a site.

That NEVER happens to me. I’ve been using Safari Technology Preview as my primary browser for over a year now and it very stable.

So I tested VP9 support using a website that checks media mime support ('https://cconcolato.github.io/media-mime-support/') and STP release 110 indeed supports VP9 on the browser side. However, YouTube did not load any VP9 video in my limited testing so far. The nice thing is VP9 decoding is provided by VideoToolbox (VT) which can be used by any macOS app (video player, transcoder etc) going forward which is great. Hopefully, they will also expose VP9 encoding functionality in VT as well.




PS: Upon further inspection, they only seem to support VP9 codec inside MP4 container for now, unless I missed something. Most if not all VP9 videos in YouTube seem to use Webm container instead of MP4. However, they seem to support Webm/VP9 on iOS so it might be coming to the macOS in the upcoming STP releases.

literally, that never happened to me. I am always updated to latest (actually on Big Sur t the moment)


Only Apple would sell 5k iMacs that only support 1080p on YouTube on their native browser. Come on, Apple, it’s 2020!
hmm, YouTube is google, they couldn't possibly be doing anything nefarious, now could they? Don't know technically why this is the case, but chances are google is using proprietary tech

No kidding, and you even tried on all browsers.
I did. I tried lynx, WorldWideWeb, Netscape 1.0, Omniweb, IE6 etc. All with the express aim of proving you can manage the basic task of pasting a url. Alas, my efforts were in vain. I await another "impressive" and "stable" effort.
