Apple Releases Safari Technology Preview 138 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 138 includes bug fixes and performance improvements for Web Inspector, CSS, Experimental Model Element, Media, Web Animation, WebAuthn, SVG, Web API, Service Workers, WebRTC, WebAssembly, 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.

Hows the adblock addon situation over at Safari~?
Nothing compares to uBlock Origin with appropriate blocklists. Apple's attempt to make Safari more "private" by restricting the extension APIs just exposes Safari users to more privacy-destroying advertising.

Some sites are just atrocious to browse without adblock~
There's plenty of options out there, but what I don't like is this cluttered mess.
I wish Safari had an overflow menu like Chrome & Firefox...

Meanwhile those of use who can’t upgrade our hardware or software are thrown under the bus. Good thing there’s alternative browsers that don’t rely on Apple’s framework. :rolleyes:

Normal safari freezes on me once a day, without fail. Acts like internet connection is no longer- and I have to kill it and re-open. Is this a thing, Or my install in anyones opinion?

Regular Safari feels experimental enough to me. I'd love it to be stable and reliable like other browsers. I guess when you don't make money off it there's no incentive.
