Apple Releases Safari Technology Preview 143 With Bug Fixes and Performance Improvements

[MacRumors]

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 release 143 includes bug fixes and performance improvements for Web Inspector, CSS Container Queries, CSS Cascade Layers, Subgrid, CSS, JavaScript, Rendering, Web Animations, SVG, Scrolling, WebAuthn, WebGL, HTML, Web API, Media, Accessibility, File System Access, and Web Extensions.

The current Safari Technology Preview release is built on the Safari 15.4 update and it includes Safari 15 features introduced in macOS Monterey.

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.

Ever single release of the Safari Technology Preview is bug fixes and performance improvements. That's literally why it exists.

It's also gives you insight to what Safari might offer in future MacOS updates. MacOS 12.3 betas offered Safari version 15.4, and the first MacOS 12.4 beta offers Safari version 15.5. I would guess the current Safari tech preview build is 15.6 now?

Safari bug fixes and improvements are always welcome.

I look forward to the day I can use Safari for full screen streaming while using subtitles. For years the display will flicker when UI (ie subtitles) change lines. It's subtle but it's there and it drives me mental.

Does it fix the heavy memory usage when compared to Brave?

It’s still on 15.4. But WebKit is newer version than the one which the latest 15.5 build is based on.

I look forward to the day I can watch a stream and it doesn’t eat up 2GB of memory and eventually give me a memory warning error about an 1hr with nothing else open.

I have Been affected by this, it is the most craziest virus or male wear that I have ever seen, the whole iPhone interface is copied or mirrored, and someone else is on the other end. It affects every single program, and it sets up shortcuts to that execute when you click on an icon/program they mirrored to send to a third-party. It uses audiobooks to read your text to them. Even if you perform a factory reset through iTunes, it still sticks with your system. There’s absolutely no way around it and I have purchased three computers and three phones in the past six months to try and fix the issue to no avail. It will redirect your phone calls and intercept every single text message, it will infect any apple product. You have slowly moving into Microsoft products, and even on my Samsung TV and LG TV. And I even thought I got rid of it one time, but when I went to the App Store, one of the apps had fewer reviews than I thought that it should have and that’s the only way I caught it because everything looked just like out of the box from Apple. Not to mention, after intentionally disabling, Siri through the screen time section, Siri still gives feedback reports in the analytics section to an unknown third-party. I’ll be surprised if this review stays.
