Enhance and customize the web browsing experience on Mac, iPhone, and iPad with Safari Extensions. Using powerful native APIs and frameworks, as well as familiar web technologies such as HTML, CSS, and JavaScript, you can easily create Safari Extensions in Xcode and distribute them on the App Store in the Extensions category or get them notarized for distribution outside the Mac App Store. And now, Xcode 12 supports the popular WebExtension API and includes a porting tool to make it easy to bring your extensions to Safari.

Blocking Content

Give users the ability to block certain content types on Safari on macOS and iOS. Built with Xcode, these app extensions are designed for speed and don’t slow down browsing. And because extensions never see what webpages users visit, user data is protected.

Extending Apps

Extend the web-browsing experience by allowing Safari to read and modify webpage content on macOS. Safari App Extensions are built with Xcode and can communicate and share data with native apps — so you can integrate app content into Safari or send web data back to your app to create a unified experience.

App Store

The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community. When your Safari Extension is ready to be released, upload it to App Store Connect for distribution on the App Store. Apple reviews all extensions and updates to ensure they work reliably. Before submitting for review, make sure to read the guidelines for extensions.

Converting Legacy Safari Extensions

Legacy Safari Extensions(.safariextz files) built with Safari Extension Builder are not supported in Safari 13 on macOS Catalina, macOS Mojave, or macOS High Sierra. The Safari Extensions Gallery for legacy extensions will no longer be available in September, 2019. Users on macOS High Sierra or later can easily find extensions on the Mac App Store by choosing Safari Extensions from the Safari menu.

If you distribute legacy extensions built with Safari Extension Builder, we recommend converting them to the new Safari App Extension format, test on the latest version of Safari 13, and submit them to the Mac App Store or notarize them for distribution outside the Mac App Store.

These days we have great choices for Web browsers: Internet Explorer, Firefox, Safari, Opera, Chrome and the list goes on.

Each browser comes with its own set of advantages and features and one of the greatest benefits of Firefox has been the ability to fully customize it through the use of plugins and add-ons.

This feature is especially important for those of you using Mac OS X, when deciding whether to pick one of the two heavyweights: Firefox or Safari.

But Safari actually does support plugins. While the choice is nowhere near as extensive as that of Firefox, there is still a good variety of them to choose from.

Here’s a list of 20 useful plugins for Safari for OS X.

Please note that many plugins work through something called SIMBL (Simple InputManager Bundle Loader), which is basically a little tool that helps developers manage and run their code as plugins for the different applications on OS X.

You can grab SIMBL for free here. If any of the following need SIMBL to run, just install SIMBL and drop the plugin file into your “~/Library/Application Support/SIMBL/Plugins/” folder, though be sure to read the instructions that come with each plugin as well.

1. Xmarks

Firefox had a very popular plugin called Foxmarks. This plugin still exists but the name has changed to Xmarks, and with the name change also came the support for other browsers, namely Internet Explorer and Safari.

Xmarks provides a seamless solution for syncing your bookmarks across many computers, as well as the ability to view your bookmarks online.

If you use several computers and want to have the same set of bookmarks across all of them without any fuss, Xmarks is the solution for you. Plugin website
