Google and Mozilla have announced updates to their respective desktop and mobile browsers, with Chrome getting performance enhancements and a sync API for apps, while Firefox adds changes to the way Do Not Track works and improvements to HTML5 compatibility.
The new versions are in the beta channel for both organisations, meaning that they are not finalised code and may be subject to change before they hit the full release build for the respective browsers.
Google's Chrome 27 gets better behind-the-scenes resource scheduling, with web content appearing on screen an average of five percent faster, according to the firm.
Most other new features are aimed at developers, such as a Sync FileSystem API for Chrome Packaged Apps, providing a mechanism with which apps can synchronise stored data across multiple devices via the user's Google Drive account.
Meanwhile, the Firefox 21 beta for Windows, Mac and Linux changes the way that its Do Not Track privacy feature operates. In addition to the 'Track' and 'Do Not Track' options, a third 'no preference' flag has been added.
However, this is still just a flag and it is entirely up to websites as to whether they honour user preferences represented by the 'Do Not Track' flag.
The latest beta of Firefox for Android includes custom, open-source fonts and HTML5 optimisations, with the result that the browser now scores 411 and 14 bonus points out of a total of 500, as measured by HTML5test.com.
