Mozilla has released the latest beta of Firefox 4 as the company continues to test the software with the aim of releasing a final version early next year.
Firefox 4 Beta 7 is between three and five times faster than previous editions, according to Mozilla, and has enhanced support for HTML 5 and 3D rendering which will benefit developers.
The addition of the JägerMonkey Just-In-Time compiler will offer faster start-up time, improved page-load speeds and better performance of web apps and games, wrote Jay Sullivan, vice president of products at Mozilla, on the Mozilla Blog.
"This update to Firefox 4 Beta incorporates hardware-accelerated graphics into the final rendering of a web site, referred to as 'compositing'. This enables web sites to load and respond faster to rich and interactive content like web games, apps or photos," he said.
"Firefox 4 Beta enables developers to render 3D graphics using WebGL. Web developers can now create spectacular games, vivid graphics and brand new visual experiences for the web, without requiring users to install plug-ins."
The software offers support for the OpenType font format so that designers and developers can create sophisticated effects by controlling ligatures, kerning, alternative characters, and small and large caps variants, Sullivan added.
Firefox 4 Beta 7 is available to download now, and those already testing the previous beta will automatically be updated to the latest version.
There will be additional betas in the coming weeks, and a final version is expected in February.
