Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced three years ago 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 80 includes bug fixes and performance improvements for WebGPU, Web API, SVG Animation, Media, CSS, Accessibility, and Web Inspector. With this release, legacy Safari Extensions are no longer supported.
The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that was released to the public in September 2018.
The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store 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.

* Legacy Safari Extensions (.safariextz files) are no longer supported. Safari App Extensions and Content Blockers, which can take advantage of powerful native APIs and frameworks as well as web technologies, can be distributed with apps in the App Store or from developers’ websites.

Someone experiences with Vivaldi?
We've used Safari many many years before, we like it's clean UI but sadly since Yosemite it has turned into a nightmare for pro use to the point we dropped it entirely, if we ever use it is to debug iOS apps and lately not even that. If by any chance you decide to give the fox a go, you'll notice how abysmal Safari has become, crashes, lags, broken scrolling, broken back behavior, inconsistent rendering, poor dev tools, many mainstream sites seem to struggle rendering and will kick fans in, free MAS extensions mostly subpar, many of the paid ones offer basic stuff you can even find built-in on other browsers, etc.
