Safari 14 added WebExtensions support, so where are the extensions?

Library Extension helps you find library books, but it doesn’t work on Safari—yet.

At WWDC 2020, Apple announced it was going to support Chrome-style browser extensions (the WebExtensions API) in Safari. But with a catch, as Dan pointed out:

Apple’s approaching this in an unsurprisingly Apple-like fashion. If you want to distribute a web extension, it’s got to be wrapped in a native Mac application designed in Xcode. Installing the app from the app store will also install the web extension.

This feature, which shipped last fall in Safari 14 (on Big Sur, Catalina, and Mojave), theoretically lets the developers of JavaScript-based extensions—for Chrome, Firefox, Edge, and other browsers—bring largely the same code and make it available to Safari users on the Mac.
