Mozilla has released the first alpha test version of Firefox 3.6. The new browser, codenamed "Namoroka", is built on the Gecko 1.9.2 platform and comes with several new features and performance enhancements. Here's the changelog for Firefox 3.6 Alpha 1:
We’ve made a huge number of improvements to overall DOM and element layout performance. In some cases we’re much, much faster. We’ll cover details on those in a later post.
The compositor landing has made it possible to fix a large number of interactions between web content, CSS and plugins. We’ll be talking about this in a later post as well.
We now support the -moz-background-size CSS property which lets you set the size of background images.
We now support CSS Gradients.
We now support multiple background images.
We now support the rem unit as a CSS unit.
image-rendering is supported for images, background images, videos and canvases.
We now send a reorder event to embedded frames and iframes when their document is loaded.
We’ve removed the getBoxObjectFor() method. It was non-standard and exposed all kinds of non-standard stuff to the web.
We now send a hashchange event to a page whenever the URI part after the # changes.
We now have Geolocation address support for user-readable position information.
We now support the complete attribute on document.readystate.
