Apple Releases Safari Technology Preview 160 With Bug Fixes and Performance Improvements

Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced 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 Feature
‌Safari Technology Preview‌ release 160 includes bug fixes and performance improvements for Web Inspector, CSS, Rendering, Web Animations, SVG, Media, JavaScript, WebAssembly, Service Workers, Accessibility, Editing, and Web API.

The current ‌Safari Technology Preview‌ release is version 16.4 and is compatible with machines running macOS Ventura and macOS Monterey.

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

Safari is the biggest pile of horse **** ever developed. It often stalls, website freeze completely, loading speeds are super slow and unresponsive. Not all the time, but it is the times you need it, it falls flat on its face. - Still using it daily because of artificial Password Limitation crap with Touch ID and Keychain. Whoever says, that Safari never hangs is using it wrong. For your daily web browsing needs, an iPod touch would be plenty. As a Full Time Developer it often frustrates me. Force Quitting is an hourly routine. THANK goodness Mapple realized it, and Macs automagically have a handy shortcut for this. Cmd + Q is the savior of all Safari Users. - PS: My colleagues think the same
This really sounds like a you problem. I'm a developer and I have been using for YEARS without many problems.

The only thing I wish Apple would do is update Safari outside of macOS updates.
They do, I'm stuck on Monterey and recently received Safari 16.2 through Software Update.

I can't use Safari - it stalls/hangs on too many websites - for now apparent reason or logic.
The minute I switch to Firefox or Edge, no such problems.
I use Safari exclusively. It NEVER stalls or hangs on any website. Whatever you are doing, stop it.

from time to time it works ... but just google the problem... it's been there since Monterey
Googling doesn’t prove there’s a problem at all. It works for me as well, always has. There’s nothing to fix.
