Mozilla Firefox 3.6 brought a handful of new features to this already excellent web browser.

First of all, the interface in Mozilla Firefox 3 is now much easier to customize. This version offers seamless integration with Personas, Mozilla's theme gallery for Firefox, which lets you apply new Firefox themes to your browser with a single mouse click. What's more, you can try them on the browser before actually applying them, just by hovering your mouse over the theme's name.

Another impressive new feature in Mozilla Firefox 3 is the native support for watching videos in full screen – as long as they've got the HTML5 'video' tag. Simply right click on the video and select the "Full screen" mode to turn the browser into a media player. Also, Mozilla Firefox 3 has released a new online service called Plugin Check, which helps you check for new updates for your plugins – quite handy, especially if you're as addicted to Mozilla Firefox 3 addons as I am!

Regarding efficiency and stability, the new Mozilla Firefox 3 includes the latest version of the Gecko engine and has improved Java performance. These two elements are meant to provide a faster web browsing – which has been its weakest point of late. While I haven't tested the final version long enough, I have to say I've been using the betas and release candidates for a while, and I'm quite happy with the program's response.

In all, the new features included in Mozilla Firefox 3 may not be as many or as spectacular as other releases, but they do provide a better user experience in terms of usability, customization and performance.

Mozilla Firefox 3 continues its steady development and adds interesting new features and improvements in its latest version.
