Apple Releases Safari Technology Preview 177 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 177 includes fixes and updates for Web Inspector, CSS, Rendering, Popover, Media, JavaScript, Web API, Accessibility, and Apple Pay.

The update now features content coming in Safari 17 alongside macOS Sonoma. On Sonoma, the browser offers Profiles for separating browsing data like History and Favorites, web apps, and improved private browsing mode. Features for all operating systems include Feature Flags (replacing Experimental Features), a redesigned Develop menu, Live Text support for vertical text recognition in images and videos, HEIC support, and JPEG XL, a new image format with an improved compression algorithm for better image quality at smaller file sizes than JPEG.

The current ‌Safari Technology Preview‌ release is compatible with machines running macOS Ventura and ‌macOS Sonoma‌, the latest version of macOS that Apple is beta testing right now.

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.

Kind of disappointed with the implementation of Profiles on Safari by Apple.

Unless I am missing something, it does not actually completely separate the different Profiles?

Like I would like to have a „Private“ and „Work“ Profile with its own Bookmarks, Saved Passwords and Reading list but as far as I could see, it just throws everything together, which makes Profiles somewhat pointless to have?

I don’t need to have my Tool logins from work saved on my Private profile, nor do I need my private bookmarks appear among my work related things

I just checked and mine has separate profiles for data history and favorites for each profiles I created.

Yes that's nice, but since most Apple computers on earth can't install it, but they can all run Safari's competitors, it hardly makes sense to have one new computer running safari when all your Intel macs have to run Firefox or Opera, or...

Together with Firefox, the only challenger to the Chromium’s dominance. We must protect it at all costs

I wish they tried another shot at releasing it on Windows

I like Safari and want to use it, but tab search is lacking. Chrome lets me move between tabs across all Chrome windows with the shift-command-A hotkey and lets me select a tab without ever leaving the keyboard. It's so annoying that Safari is almost functional, but drops the ball at the finish line forcing me to click the tab.

If only I could install uBlock Origin on it, I would switch to Safari as my main browser immediately. :apple:

...but I can't, so I'm still on Firefox. ?
