While many are celebrating the Summer Solstice, Mozilla developers are celebrating the rapid release of Firefox 5.
Although the latest version reportedly includes more than 1,000 improvements and performance enhancements, the update from version 4 to version 5 feels more like a security update than a new version.
As indicated at Security Advisories for Firefox, the vulnerabilities listed below were Fixed in Firefox 5. This includes the WebGL graphics memory stealing issue addressed in at Mozilla Security Blog.

One other important item is the end of life (EOL) for Firefox 4. Those running 4 will no longer receive security updates - they need to move to 5.

Also, although this is about Enterprise use of Firefox, based on Asa's remarks, we can expect the same version upgrade with the next accelerated releases. From the comments starting at http://mike.kaply.com/2011/06/23/understanding-the-corporate-impact/#comment-10493:
Quote: "Firefox 6 will be the EOL of Firefox 5. And Firefox 7 will be the EOL for Firefox 6."
BTW, in case you missed it, the "Do not track" option is opt-in. It is located on the Privacy tab in Options.
