Mozilla keeps on truckin'.

A mere 3 months after releasing a major update the Mozilla Foundation is at it again with Firefox 5. Download and give what many (myself included) consider to be the web's best browser a try. Improvements include:

• Better standards support for HTML 5, CSS3, MathML, XHR and SMIL
• Better visibility for the Do not track header preference
• Stability and security improvements
• Improved canvas, JavaScript, memory, and networking performance
• Improved spell checking for some locales

While you're at it, try their excellent email client, Thunderbird, as well. The web works better when unencumbered.
