While the official announcement of Mozilla Firefox 5 Final release is still not made, as happened in the past the Firefox 5 Final release build is already available on official Mozilla FTP servers, open to public access. The official scheduled date for Firefox 5 launch is after two days on 21st June, but the download is now online so nobody is stopping us to enjoy it before release date.

Direct download links for Firefox 5 Windows, Linux and Mac versions, change-log and a memory usage comparison to Firefox 4 posted after the jump.

The latest version of Firefox has the following changes:

• Added support for CSS animations
• The Do-Not-Track header preference has been moved to increase discoverability
• Improved canvas, JavaScript, memory, and networking performance
• Improved standards support for HTML5, XHR, MathML, SMIL, and canvas
• Improved spell checking for some locales
• Improved desktop environment integration for Linux users
• WebGL content can no longer load cross-domain textures
• Background tabs have setTimeout and setInterval clamped to 1000ms to improve performance
• The Firefox development channel switcher introduced in previous Firefox Beta updates has been removed

As there were talks of improved memory handling in Firefox 5 and the announcement of Mozilla's mission MemShrink, I was hoping for some measurable affects here but this does not seems to be the case with this release. Below is a comparison of Firefox 4 and Firefox 5 in real-life scenario both having same numbers of tabs loaded on same computer configuration.
