Apple Reminds Developers That Safari 14 Supports Extensions Ported From Chrome, Firefox, and Edge
Apple this week reminded developers that they can create web extensions in Safari 14 using the same WebExtensions API used in other browsers, such as Chrome, Firefox, and Edge. A new conversion tool in Xcode 12 beta also allows developers to port existing extensions from other browsers to Safari and make available on the Mac App Store later this year.

Apple says developers have two options for creating Safari web extensions:
• Convert your existing extension into a Safari web extension, so you can use it in Safari on macOS and distribute it in the App Store. Xcode includes a command-line tool to simplify this process.
• Build a new Safari web extension in Xcode using the built-in template. You can then repackage the extension files for deployment in other browsers.
Safari web extensions are available in macOS Big Sur and in macOS 10.14.6 or 10.15.6 with Safari 14 installed.
Not all Chrome, Firefox, and Edge extensions will work in Safari, and developers will be required to pay $99 per year for an Apple Developer Program membership in order to port their extensions to Safari. Apple has a WWDC video and documentation with more details for developers.
