HTTP Strict Transport Security (HSTS) is a security standard that provides a mechanism for web sites to declare themselves accessible only via secure connections, and to tell web browsers where to go to get that secure version. Web browsers that honor the HSTS standard also prevent users from ignoring server certificate errors. Apple uses HSTS on iCloud.com, for example, so that any time a visitor

WebKit on iOS has a 350 millisecond delay before single taps activate links or buttons. WebKit has this delay because we also allow users to double tap to zoom, which is a great way to zoom in on content that is well-sized for large desktop displays, but appears too small on mobile devices. However, when a user has tapped once, WebKit cannot tell if the user intends on tapping again to trigger a d

As web content has become increasingly interactive, responsive, and complicated, ensuring a good user experience across multiple platforms and browsers is a huge challenge for web developers and QA organizations. Not only must web content be loaded, executed, and rendered correctly, but a user must be able to interact with the content as intended, no matter the browser, platform, hardware, screen

When implementing new features for the Web, it’s important for us to be able to get them into the hands of developers early, so they can give new things a try. (Of course, this also helps us identify and fix bugs!) In the past, browsers did this by using vendor-prefixed names for features. This was intended to protect the Web from the churn of spec and implementation changes. Browsers would eventu

Ten years ago today we introduced the first version of Web Inspector to the world. That time was the wild west of web development, when your best debugging aid was alert(). While the earliest version of Web Inspector was limited (it didn’t even have a console), it did expose two things that developers didn’t have much insight into — the DOM tree and matching style rules. Web Inspector being open s

A typical website is made of numerous components coming from a wide variety of sources. Many of the sources that make up a website are opaque to the user, and some third-party resources are designed to identify and track users as they browse the web, often in order to retarget ads and measure ad campaign effectiveness. The combination of third-party web tracking and ad campaign measurement has led

Security researchers have recently uncovered security issues known as Meltdown and Spectre. These issues apply to all modern processors and allow attackers to gain read access to parts of memory that were meant to be secret. To initiate a Spectre- or Meltdown-based attack, the attacker must be able to run code on the victim’s processor. WebKit is affected because in order to render modern web site

Since before your sun burned hot in space and before your race was born, Safari on iOS has required a user gesture to play media in a <video> or <audio> element. When Safari first supported <video> in iPhoneOS 3, media data loaded only when the user interacted with the page. But with the goal of returning more control over media playback to web developers, we relaxed this restriction in iOS 8: Saf

When we invented Private Browsing back in 2005, our aim was to provide users with an easy way to keep their browsing private from anyone who shared the same device. We created a mode where users do not leave any local, persistent traces of their browsing. Eventually all other browsers shipped the same feature. At times, this is called “ephemeral browsing.” We baked in cross-site tracking preventio
