Apple Releases Safari Technology Preview 165 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 165 includes bug fixes and performance improvements for Web Inspector, CSS, JavaScript, Layout, Media, Forms, Web Animations, WebCrypto, WebGL, Loading, Web API, Accessibility, and Web Extensions.

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.

Wasn't there supposed to be some new Safari extension framework that was more interoperable with Chrome extensions? I recall something being said about that a while back. Safari extensions are both weirdly rare and hard to search through.

Happy camper with Edge. Also have STP installed and try it from time to time, what a joke of browser. You will be blown away by the "less worse" desing and features of Edge. Collections, bookmark management, strat page with my favorite sites is BASIC and Apple removed that years ago and made Safari a lackluster product that is brings no joy in using the internet...
Just kill it, Apple. It is pathetic since many years ago and there is no indication that a capable human is designing the user experience in Safari.
Edge sucks, IMHO. Tried it, hated it. Plus it is a lot slower

There is (''). It was introduced at WWDC 2020 and there's a tool for automatically(-ish) converting Chrome extensions. I don't think Safari supports everything Chrome does, which prevents µBlock, for example. They may be limited for privacy reasons, as Apple usually claims, or maybe they're just not a priority. You need to pay for the developer program and I'd imagine that puts off a lot of extension developers. See

It's a work in progress:

Basically they're working through the Webextensions API with the focus being on harmonising and documenting then once done the respective browser engineers implement it with some browsers implementing it a lot quicker than others depending on how much legacy code can be refactored and bought into compliance with the API.

Really wish Apple would continue to support Safari in older Macs. While I do use other browsers at times...I do enjoy the convenience of continuing of a website I had open on another Apple devices.
