We built Safari to be the best browser for your Mac, iPhone and iPad. Built-in privacy features keep your browsing your business. You can stream and search smarter with handy tools that help you save, find and share your favourite sites. Safari for Mac is faster and more energy efficient than other browsers. And thanks to iCloud, Safari works seamlessly with all your devices.

• Get Firefox, a free web browser backed by Mozilla, a non-profit dedicated to internet health and privacy. Available now on Windows, Mac, Linux, Android and iOS.
• Inspector is a 'lite' version of Firebug: The interface is not as good IMO, element inspection in both recent versions is now clunky, but Firebug is still better; I find myself trying to find the love for Chrome (since it's a better, faster browser experience), but for development work, it still just sucks for me.

Defending your online privacy and security.

Privacy and security aren’t just something you should hope for — they’re something you should expect. That’s why features to help protect your privacy and keep your Mac secure are built into Safari.

Intelligent Tracking Prevention.

Remember when you looked at that green mountain bike online? And then saw annoying green mountain bike ads everywhere you browsed? Safari uses machine learning to identify advertisers and others who track your online behaviour, and removes the cross‑site tracking data they leave behind. So your browsing stays your business. And Safari keeps embedded content such as Like buttons, Share buttons and comment widgets from tracking you without your permission. We know you’ll like that.

Sandboxing. Built-in protection for websites.

Sandboxing provides a safeguard against malicious code and malware by restricting what websites can do. And because Safari runs web pages in separate processes, any harmful code you come across in one page is confined to a single browser tab, so it can’t crash the whole browser or access your data.

Fingerprinting defence.

When you’re online, the characteristics of your device can be used by advertisers to create a “fingerprint” to follow you. Safari thwarts this by only sharing a simplified system profile, making it more difficult for data companies to identify and track you.

Protection from harmful sites.

Safari helps protect you against fraudulent websites and those that harbour malware — before you visit them. If a website looks suspicious, Safari prevents it from loading and warns you.

Private Browsing.

When you use Private Browsing, Safari doesn’t remember the pages you visit, your search history or your AutoFill information. You can also use DuckDuckGo, a built-in search engine that doesn’t track you, to make your web searches private too.

More secure and convenient passwords.

Safari works hard to make sure your passwords are robust and unique by automatically creating and storing strong passwords for you. Once stored, your passwords will autofill in websites across all your Apple devices and in apps on iOS and iPadOS devices. In Safari preferences, passwords that have been used more than once are flagged so you can easily update them. And one-time security codes sent over SMS are autofilled directly in the password field as soon as they appear in Messages. Security has never been so user friendly.

Surf seamlessly across all your devices.

Not only does Safari come on every Mac, it comes on all your iOS and iPadOS devices. And thanks to iCloud, your passwords, bookmarks, history, tabs and Reading List are always up to date no matter which device you’re using.

Firebug For Chrome

iCloud Keychain securely stores your user names, passwords and credit card numbers, and keeps them up to date on your trusted devices. So you can easily sign in to your favourite websites — as well as in apps on iOS and iPadOS — and quickly make online purchases. And everything is protected with robust 256-bit AES encryption.

With Bookmarks in Safari, your favourite sites are always close at hand. Bookmark a web page on your Mac and it automatically appears on all your iCloud-connected devices.

With Tab view, the last websites you had open on your Mac are available in Safari on your iOS and iPadOS devices — and vice versa. So you can go from one device to another without having to search for the web pages you were reading.

Save web pages you want to read later simply by adding them to your Reading List. Then view them on any of your iCloud-connected devices — even if you’re not connected to the Internet.

The fastest way to browse on a Mac. And faster than any Windows browser too.

With an incredibly fast JavaScript engine, Safari is the world’s fastest desktop browser, outperforming both Mac and PC browsers in benchmark after benchmark on the same Mac.¹

Search more. Stream more.

Safari is optimised specifically for Mac, so it’s more efficient than other browsers on macOS. And Safari plays HTML5 video — the format used by your favourite streaming services — whenever it’s available. So you can explore the web for up to three hours longer and stream video for up to four hours longer than on any other browser.²

The best browsing experience.

Features in Safari help you surf smarter and easily manage and share what you find.

Updated start page. Easily and quickly access your favourites and frequently visited sites. And Siri suggestions surface bookmarks, links from your reading list, iCloud Tabs, links you receive in Messages and more.

Desktop-class browsing on iPad. Safari now shows you a website’s desktop version that’s scaled for the large iPad display and automatically optimised for touch input. Faster and more fluid scrolling makes browsing feel better than ever. And a new download manager means you can easily download and share files directly in Safari.

Stop auto-play videos. Safari prevents unexpected and unwanted videos with audio from automatically playing while you browse. Just click the play button if you want to view them. Have a favourite site where you always want videos to play? Use per‑site settings in Safari to enable media auto-play.

Turn on website icons in tabs in Preferences to easily see what you have open. Pin your favourite sites and they’ll reappear in tabs every time you open Safari. You can also mute the audio on any tab directly from the Smart Search field — perfect for stopping the music without having to hunt for where it’s coming from or, if you prefer, silencing all the audio from your browser at once.

Personalise your browsing experience in Safari with settings for individual websites, like page zoom level, location services and content blockers. So each website appears just how you like it.

Automatically use Reader for every web article that supports it, so you can read without ads, navigation and other distractions. Customise your view by selecting your font size and style, and choose Sepia and Night themes.

Get Firebug

Play video from a web page to your TV with Apple TV — without showing everything else on your desktop. Just click the AirPlay icon that appears on compatible web videos and you can watch your video on the big screen.

Float a video window from Safari over your desktop or a full-screen app on your Mac or iPad. Play the video in any corner of the desktop and resize it to see more or less of what’s behind it. So you can watch videos while you browse photos. Or catch up on your favourite show while you catch up on email.

With Spotlight built into every Mac, you’re never far from the information you want. As you type in the Smart Search field, you’ll see Safari suggestions from sources like Wikipedia, news sites, Maps, movie listings, flight status, weather, stocks and sport.³

Share anything you come across on the web without leaving Safari. Just click the Share button, then choose how you want to send it off. Use Mail, Messages or AirDrop or add it to a note.

Developers

Deep WebKit integration between Mac hardware and macOS allows Safari to deliver the fastest performance and the longest battery life of any browser on the platform, while supporting modern web standards for rich experiences in the browser. WebKit in macOS Catalina includes optimisations and support for additional web standards that enable even richer browsing experiences.
