Et voici une nouvelle version alpha de la prochaine version de Firefox. On ne sait toujours pas laquelle, mais elle est pour l'instant numérotée 3.7 et libellée "Developper Preview". Sur cette alpha, les développeurs du navigateur ont réalisé quelques avancées dans le domaine de la gestion multi-processus des plugins, ainsi que dans le domaine du HTML5/CSS/DOM/WebGL et Javascript.
Voici d'ailleurs en résumé, toutes les nouveautés :
New Features and Changes
Gecko 1.9.3 Alpha 2 introduces new features which can be tested by using this Mozilla Developer Preview. Many of these features are still in development, and while they will likely appear in some future version of Mozilla Firefox, some may be in earlier releases than others.
Plugins On Windows and Linux, plugins (such as Flash and Silverlight) are now isolated from Firefox. Plugin crashes will not kill Firefox itself, and unresponsive plugins are automatically restarted. Security The SSL security system has been changed to fix a renegotiation flaw. For technical details, see the newsgroup posting announcing the change. Performance Link history lookup is now performed asynchronously on a thread. This results in less I/O during page load and improves overall browser responsiveness. Performance Loading the HTML5 specification no longer causes very long browser pauses. See bug 526394 for details. JavaScript The JavaScript engine has many improvements: string handling is improved, faster closures, and some support for fast tracing and JIT of recursive functions. Performance Strings are not copied between the main DOM code and web workers, improving performance for threaded JavaScript which moves large pieces of data between threads. HTML The placeholder attribute for <input> and <textarea> is now supported. User Interface The stop and reload buttons have been merged when they are adjacent on the toolbar. See bug 343396 for details. SVG Support for SMIL Animation in SVG. Support for animating some SVG attributes is still under development and the animateMotionelement isn't supported yet.Stability Crash reports from plugin processes are now submitted automatically. Crash report submission can be disabled in Firefox preferences (Advanced / General / Submit crash reports). Performance Repainting HTML in SVG <foreignObject> is faster. See bug 541188 for details. CSS Support for CSS Transitions. This support is not quite complete: support for animation of transforms and gradients has not yet been implemented. WebGL Support for WebGL, which is disabled by default but can be enabled by changing a preference. See this blog post and this blog post for more details. DOM Support for the getClientRectsandgetBoundingClientRectmethods onRangeobjects. See bug 396392 for details.DOM Support for the setCaptureandreleaseCapturemethods on DOM elements. See bug 503943 for details.HTML Support for the HTML5 History.pushState()andHistory.replaceState()methods and thepopstateevent. See bug 500328 for details.CSS Support for the -moz-image-rect()value forbackground-image. See bug 113577 for more details.We are interested in feedback on any bugs or missing capabilities in these new features. Some of the changes will affect web and platform compatibility.
