We already know that Mozilla’s Firefox roadmap is falling behind, but that’s not all. They now seemed to be desperate in pushing Firefox 5 out.

Mozilla has pushed the Firefox 5 Beta 1 out and made available for download for Firefox 4 users, hoping that adoption rate will be increased. This is part of the company’s plan to move to a faster release cycle designed to get experimental builds of the web browser out to a wider audience.

The first beta release of Firefox 5 adds support for CSS animations, which allow developers to animate transitions between CSS states. For a list of all the animations Firefox 5 currently supports, head over to the Mozilla developer page (note that all the supported rules currently require the -moz prefix).

Firefox 5 beta sees some performance improvements to JavaScript, memory, and networking performance. There’s also been some speed boosts for canvas-based animations. Other new features include improved support for web standards like HTML5, XHR, MathML and SMIL, along with the usual bug fixes that come with any beta release.

The desktop version Firefox isn’t alone this time either. To go along with the new desktop beta, there’s also a new beta of Firefox 5 for mobile devices. Firefox 5 beta for mobile adds support for the Do Not Track header and offers some speed improvements, particularly on 3G networks.
