New in this new version, found among other things the Gecko rendering engine version 1.9.1, a new method of navigation private as well as new options to erase their tracks after a session online.
Firefox 3.1 Beta 2 also loads a corrected version of TraceMonkey, the new execution engine used by Mozilla JavaScript, whose performance and stability should have been increased as compared to the first beta. TraceMonkey is now enabled by default on Web content.
This Beta 2 also introduces the "DOM Worker Threads", a technology that will be relegated in the background running some sections of code, and improves care items and as well as some properties of CSS (Cascading Style Sheets) 2.1 and 3.0.
Firefox also gets a module allowing pre DNS, the goal here is to reach diminish the page load times. Initially thought to Firefox Mobile (Fennec), this feature is to browse the contents of a Web page, and make it look up on each of external links contained in it, an operation that is to go interview the DNS servers to obtain, from the domain name involved, the physical address of the machine that hosts the site that you might want to display then.
