Just three months after the release of Firefox 4, Mozilla has pushed out Firefox 5 for the desktop and Android devices.

That’s a big change from the two years it took to move from Firefox 3.5 to Firefox 4. Firefox 5 is part of Mozilla’s new rapid release development cycle. This cycle, which is more akin to what Google does with its Chrome browser, promises faster, more iterative updates. With any luck, Mozilla expects Firefox to hit version 7 by the end of the year.

Sure enough, though, Firefox 5 was officially released on Tuesday complete with a raft of new features that promise to give the browser yet another boost. Here are five good reasons you should download Firefox 5 as soon as you can.

1. It Respects Your Privacy

Mozilla’s Do Not Track feature gives users more control over the way their browsing behavior is tracked and used on the Web by allowing them to tell the websites they visit that they want to opt out of online behavioral tracking. Now, in Firefox 5, Do Not Track is even easier to find in the Firefox Preferences section.

Also of note is that Firefox 5 for Android includes the Do Not Track feature as well, making Firefox the first browser to support Do Not Track on multiple platforms, Mozilla says.

2. It’s Small and Fast

I’ve been feeling like Firefox 5 is faster, and that impression was recently confirmed over at Digitzor, which ran it through a bunch of benchmarks. Firefox actually blew away both Chrome and Opera on the SunSpider JavaScript test, in particular (no other browsers were included), and its cold start time compared very well with that of Google’s Chrome. Firefox 5 was also notable for taking up minimal RAM, even with 25 websites opened.

3. It Supports an Open Web

With improved standards support for HTML5, XHR, MathML, SMIL and canvas, Firefox 5 is the best browser choice for an open Web. The new Firefox Add-on SDK for Windows, Mac and Linux enables local development of add-ons, meanwhile, and the Firefox Add-on Builder Beta provides a hosted Web-based build environment. The new version of the multiplatform software also adds support for CSS animations.

4. It Sports 1000 Improvements

It’s actually more than 1000 improvements and performance enhancements that have been included in Firefox 5. They may not all be huge, noticeable user-interface changes, but they definitely make the software better.

The Android version of Firefox 5, meanwhile, includes a raft of bug fixes, improved page load speeds–especially on 3G networks–and added IPv6 support.

5. It’s Secure, Independent and User-Driven

Firefox is open source software, which means it’s not only developed with the help of users, but its security is continuously monitored and improved by a global community of users and developers. Mozilla, meanwhile, is an independent foundation. There’s no way a proprietary browser maker like Microsoft — or even a company like Google, which has its fingers everywhere — can compete with that independence and user focus.

  1. I’m anxious to check it out. I didn’t upgrade to FF4 because I wanted the dust to settle first. Anyone who may come across this post who’s downloaded and are using FF5, how did the previous add-ons work, were there compatibility issues? Thx.

  2. Firefix 5 is becoming more and more appealing than chrome!
    The awesome bar is much much better that chrome’s omnibar.
    Also memory requirements are much less when opening many tabs.
    thumbs up Mozilla
