Apple Releases Safari Technology Preview 233 With Bug Fixes and Performance Improvements

by

Apple today released a new update for Safari Technology Preview, the experimental browser that was first introduced in March 2016. Apple designed ‌Safari Technology Preview‌ to allow users to test features that are planned for future release versions of the Safari browser.

Safari Technology Preview Updated Feature 1
‌Safari Technology Preview‌ 233 includes fixes and updates for Animations, HTML, MathML, Rendering, Web API, and Web Inspector.

The current ‌Safari Technology Preview‌ release is compatible with machines running macOS Sequoia and macOS Tahoe, the newest version of macOS.

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 from Apple's website. Complete 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 it is designed for developers, it does not require a developer account to download and use.

Never really was since it’s not a good browser. Firefox is snappier
What do you do guys with your browsers? Browsing competitions? To me, speed is the least important factor in deciding which browser to use. Nowadays they're all pretty fast.

I look forward to the day when macstories actually offers useful information related to these updates rather than a glorified update notification wrapped as a blog article.

What year is it where you are? In 2025 Firefox and all Gecko based browsers are the slowest and least compatible by far, it's well on its way to irrelevance at this point, and believe me that's not something I am happy to report. The Chromium monopoly is reminiscent of IE in the late 90s / early 00s, WebKit is the only real competitor and that's only because Apple doesn't allow other browser backends on iOS. Normally I'd be against that kind of thing, but since it's the only reason Chromium isn't completely dominant, I'm not sure.

Let's also remember Chromium is itself a fork of WebKit, if you really want to think of how incestuous the current browser landscape is.

Scrolling being smooth with low input latency changes the whole experience, makes it more efficient and more pleasant to use. Loading speed obviously matters as well and that depends not only on your internet speed.
That being said, in my experience Safari literally is the fastest/smoothest browser when comparing apples to apples (same ad blocking settings etc).

Can't comment about this specific TP version though. I've tried it a couple of releases back and found it to work worse than the current stable version.
