Mozilla releases Firefox 5

Filed under
Moz/FF

As expected, the Mozilla Project has released version 5.0 of Firefox. The update to the open source web browser comes just three months after the project's last major version, Firefox 4.0, which suffered a number of delays – Mozilla has adopted a version model similar to that used by Google for its Chrome browser.

One of the most important additions in Firefox 5 is support for CSS animation, a feature that browsers such as Safari have offered for some time. When creating a CSS animation, a developer specifies the animation's duration and name in the CSS rules for the HTML element in question. The @keyframes selector associated with this name is followed by the rules that describe the element's beginning and end points as well as optional intermediate stages.

The Do-Not-Track header preference has been moved "to increase discoverability". On Windows, it can be found under "Tools->Options->Privacy", while on Mac OS X, it is under "Firefox->Preferences->Privacy". This preference allows users to tell web sites that they don't wish to have their browsing behaviour tracked.
