Apple Releases Safari Technology Preview 150 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 150 includes bug fixes and performance improvements for Web Inspector, CSS, Shadow DOM, JavaScript, Web Animations, Web Share, WebAuthn, Web API, Rendering, and Accessibility.

The current ‌Safari Technology Preview‌ release is built on the Safari 16 update and it includes support for feature coming in macOS Ventura such as Live Text, Passkeys, Web Extension improvements, and more.

The new build of ‌Safari Technology Preview‌ is compatible with machines running macOS 13 Ventura, unlike prior versions of ‌Safari Technology Preview‌, but it no longer works with macOS Big Sur.

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.

Who uses Safari anymore?.
I switched to Edge and I am mediocrely happy with it, which is light years less terrible user friendly than Safari. Not sure I made sense :)
The pinned home page was good and when Apple removed it, along with the 1998 bookmarks management interface I switched to a 2005 style browser. Ah, the good old days of 2015 when Safari was “fast and focused”…
Bookmarks management sucks, but Safari's the fastest browser.
I can't trade it for anything else at the moment.

I keep running into this Safari bug (?) where I'll go to a url in a new tab and it'll quickly flash the page before going back to an empty tab.

I gave up on safari recently due to very limited content blocking options. Webpages recently become such a mess with miriads of different cookie popups etc. that trying to use them without content blocking is not particularly pleasant. Firefox does it way better. It's a shame really as Safari is best integrated with macOS, and in my opinion faster.

Fastest? lol.. try the others, seriously.. even swiping back & forth pages it's probably among the slowest ones.

Bookmarks management suck? What about extensions? dev tools? tab groups? cookie management? privacy tools? RAM management? no built-in ad blocker, compact view with the same UI glitches since beta 1, sometimes even icloud.com fails to load while working fine in other browsers, media playback is a pandora box depending the site, issues with most productivity domains from Google, Atlassian, Microsoft, etc, etc, etc, etc, etc, etc, etc, etc.
Wow! I wish that I had your "milli-second response" eyes! Seriously though, Safari loads cached pages very, very fast, and using far less resources than Chrome-based browsers.

Something that is worrying me, and I know many others too, is the move towards the bad-old days of "works best with..." or "only works with...". Apparently, we are no better than our predecessors. I am disappointed that so many users on this forum are helping to make this happen.
