Web platform features explorer - August 2013 release notes

New in Chrome

The following features are now available in Chrome:

Flexbox: Flexbox is a one-dimensional layout system, which places content either horizontally or vertically, with optional wrapping.
OES_texture_float_linear WebGL extension: The OES_texture_float_linear extension for WebGL 1.0 and 2.0 contexts adds linear filtering with floating-point pixel types for textures.
OES_texture_half_float_linear WebGL extension: The OES_texture_half_float_linear extension for WebGL 1.0 contexts adds linear filtering with half floating-point pixel types for textures.
Resource timing (initial support): PerformanceResourceTiming entries report when network events happen while loading a resource, such as when connections start and end. You can use this information to measure loading times.

The following features are now available in Firefox:

Content Security Policy (CSP): Content Security Policy (CSP) helps to mitigate certain security threats, including cross-site scripting (XSS) and clickjacking attacks. It consists of a set of directives from a website to a browser, which instruct the browser to restrict the things that the site is allowed to do.
document.caretPositionFromPoint(): The document.caretPositionFromPoint() method finds an insertion point, represented by a DOM node and an offset within that node, for given coordinates in the viewport.
<input type="range">: The <input type="range"> element represents a slider for choosing an inexact value between a minimum and maximum value.
requestAnimationFrame(): The requestAnimationFrame() method schedules a function that runs before the next repaint. You can use it to animate content with JavaScript.
