Introduction to WebKit Content Blockers
Browser extensions have been a big part of modern browsers for a while now. With extensions, everyone can change their browser to their preferences. Today, there are several models to extend browsers. Most extensions are written in JavaScript and loaded by the browser, following a model introduced by Mozilla over a decade ago. That model is also used with WebKit. It is the classical way to write e
Introducing the JetStream Benchmark Suite
Today we are introducing a new WebKit JavaScript benchmark test suite, JetStream. JetStream codifies what our de facto process has been — to combine latency and throughput benchmarks with roughly equal weighting, and capturing both metrics of traditional JavaScript programming styles as well as new JavaScript-based technologies that have captured our imaginations. Scores on JetStream are a good in
Speedometer: Benchmark for Web App Responsiveness
Today we are pleased to announce Speedometer, a new benchmark that measures the responsiveness of web applications. Speedometer measures simulated user interactions in web applications. Version 1.0 of Speedometer uses TodoMVC to simulate user actions for adding, completing, and removing to-do items.

Apple style span is gone
This week, I committed WebKit changes r92823 and r93001. They’re perhaps the most important changesets I’ve ever committed to the WebKit codebase because these changesets made WebKit no longer produce wrapping style spans on copy and paste and class="Apple-style-span" anymore. In fact, these are two changes I’ve always wanted to make ever since I started working on the WebKit’s editing component i

As you might know, WebKit Web Inspector is implemented as an HTML + CSS + JavaScript web application. What you might not know is that Web Inspector can run outside of the browser environment and still provide complete set of its features to the end user. Debugging over the wire Running debugger outside the browser is interesting because mobile platforms do not often provide enough screen real esta
Surfin' Safari - Blog Archive » Web Inspector: Understanding Stack Traces
Finding errors in JavaScript code both during application development and when it’s already released is an important part of web development. We’ve recently added a mechanism for handling uncaught JavaScript exceptions and made some improvements in the tools that allow you to work with stack traces. Now it’s a good time to summarize the ways one can deal with exceptions and stack traces in WebKit.

Recently some changes to the User Agent (UA) string have landed. These changes are designed to add UA string detail, remove redundancy, and increase compatibility with Internet Explorer, and are happening in conjunction with similar changes in Firefox 4.
