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 release 130 includes bug fixes and performance improvements for Web Inspector, CSS, JavaScript, Media, Web API, and IndexedDB.

Apple warns that Tab Groups do not sync in this release, and on macOS Big Sur, users need to enable GPU Process: Media from Experimental Features under the Develop menu to address issues with streaming services.

The current Safari Technology Preview release is built on the new Safari 15 update included in macOS Monterey, and as such, it includes several Safari 15 features. There's a new streamlined tab bar with support for Tab Groups to organize tabs, along with improved support for Safari Web Extensions.

Live Text allows users to select and interact with text in images on the web, but the macOS Monterey beta and an M1 Mac is required. There's also Quick Notes support for adding links and Safari highlights to remember important information and ideas.

Other updates include WebGL 2 and new HTML, CSS, and JavaScript features.

The new Safari Technology Preview update is available for both macOS Big Sur and macOS Monterey, the newest version of the Mac operating system that's set to release this fall.

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.

Not seeing the update yet. I hope they've fixed the Side Bar stretching all the way to the top as opposed to in Safari Version 14.1.2 that lets you keep the Side Bar open just on the Start Page. With the Tech Previews, that Side Bar has been extending ALL the way to the top, meaning you'd have to keep the Side Bar visible full time, regardless of what web site you're at. I like having the Side Bar open on the Start Page, but then don't need it when I navigate away.

Please fix the random reload of Safari’s tabs! Keep getting error “Webpage was reloaded because it using high resources…” 😡
I've just started seeing a message like that in regular Safari the last week or so, but I don't think it reloads anything. I've also seen something like (regular Safari) 'background processes' going crazy on a bad connection and spawning multiple ssh processes that suck up a lot of power, but don't transfer anything. Too much going on the background these days for no good reason.

I’ve switched to Chrome on all of my Apple products… couldn’t be happier! Just too many issues with Safari… pages not loading correctly… pages not functioning correctly… tabs constantly reloading… memory/energy warnings all the time. Make the switch. Everything just works with Chrome. Faster too.

I have the opposite experience than you (coming from chrome). Safari is faster and with better UI. And chrome consumes much more energy.

No, Side Bar still isn't fixed.

Weird. I keep giving Safari a chance and always end up going back to Chrome. I do web development and Chrome is far superior for that.
I 100% agree there. Chrome has far better dev tools. Plus it's the browser engine we can expect most users to have.

Of course it consumes less, packs half baked stuff all over it.

Dev tools are pretty poor, extension ecosystem is laughable, responsive mode behavior is subpar & outdated, privacy tools also half baked (just a checkbox to stop tracking, no individual site manipulation, no built-in adblocker), cookies management also poor, media & sound handling is an abomination they can't seem to figure out since like Yosemite, etc, etc.

Yes, the UI is much better, but thats pretty much it sadly.. a cute UI. The new IE on a pretty UI.

If a page is opening SSH then run away from that site. Even if it is not transferring anything it can accept commands from a remote server.

Battery dies faster too with Chrome.

What is wrong with the cookies management? Find the site and delete. That is the same one all browsers. What sound issues are you having? I know many complain about not "autostart" the playback but that is not an issue. That is a fix thanks to the tons of **** ads on legit sites.

I’ve stopped playing w these Safari Previews because they are just buggy as hell. I do use Safari for everything these days and it’s really fast and fun. The days when I had to use a different browser seem to be over. My fallback browser is Firefox, all I’ve done with it is keeping it updated.

One of the ones that come up with the 'excessive amount of power' message is MacRumors. :) Reddit may have been another, but that might have been like a news site via a link in a post.

Later (had to get out of bed and plug in my laptop):

The other thing that goes nuts is Safari Web Content (Cached), which seem to accumulate as you have more tabs open. Again, this is regular Safari (14.1.2). Maybe I'll start a thread for this...but so far it has been behaving itself now that it is plugged in to power. Hmm.

It's concerning that they are having so much trouble with sidebar.
Also tabs are still unpolished mess, what used to be simple drags and flicks to rearrange tabs is now uncertainty if your drag will even pick up a tab and if it will pick it up you have to be precise with your drags and drops, you can't just flick them around like you used to.
