Here’s how to install Firefox OS 2.5 Developer Preview experimental app on your Android device to experience and test drive Firefox OS.

It seems that the team behind the popular Web browser Firefox may be working on an iOS version of the app according to new reports.

Firefox has been one browser that has improved a lot over time, and while Internet Explorer continues to receive the negative feedback from users across the globe, Mozilla’s offering has actually grown into a worthy contender against almost any internet browser, most notably Google Chrome. Mozilla’s focus towards bringing the best of the best to its users continues, and with the release of Firefox 20, they’ve brought some much needed (and appreciated) enhancements to their already popular browser. The new Firefox 20 has not only been released for desktop systems – including Windows, OS X and Linux – but also for Android, albeit with a slightly different change log. Let’s take a look at what’s new and improved just past the fold.

Firefox OS, Mozilla’s attempt to make a dent into the crowded smartphone market, has reached another milestone today with the release of Firefox OS Simulator 3.0, the new developer tool that allows developers and smartphone enthusiasts alike to give the smartphone operating system a try, straight from their computers.

Throughout the history of iOS, several third-party browsers have made it to the platform, although the built-in Safari browser is the only one that can be integrated deeply into the system. At a panel at SXSW, a conference taking place in Texas, Mozilla Vice-President of Product Jay Sullivan made it clear that Firefox will not be making its way to iOS until Apple opens up to third-party browsers.

Mozilla’s attempt at a mobile OS has been a long time in the works. The open source smartphone and tablet operating system first began back in 2011, since which the Mozilla team has regularly kept us posted with various updates and info. An appearance at CES on an unspecified smartphones, followed by the release of a couple of developer handsets late last month has certainly heightened general interest, and those keen to get started with Firefox OS may only have a short wait left. According to a press release, the European market will see the first smartphone running Mozilla’s new OS via the Alcatel One Touch, which will first arrive in Poland venturing west across mainland Europe.

Mozilla’s biggest export is Firefox, and with Windows 8 having been in circulation for a few months now, the next stage of preparations for a version of the popular browser tailored to Microsoft’s latest OS release have begun. Last week, the Metro/Modern-ized browser reached Mozilla’s nightly build channel, and today, it has reached Mozilla-central. Although Firefox desktop product manager Asa Dotzler confessed there is still “plenty of work” to be done, it has now reached a point where it is stable enough for regular testing.

Windows Phone 8 is on the up these days accompanied by fantastic devices like the Lumia 920, but it seems to be the emerging Firefox OS that is gathering interest as a newcomer to the scene. Although extremely early builds of the operating system have been released for those daring enough to try it out, not many people have witnessed it in the flesh, that is until it appeared on a mysterious smartphone during a CES event.

The Mozilla team has been busily updating and improving its revered Firefox browser, with more frequent release cycles in place to ensure it maintains competitive with the likes of Google’s Chrome. As planned, the foundation has released version 1.0 of the Firefox OS Simulator, and by means of a blog post, Mozilla has also introduced per-window private browsing via the Firefox Nightly channel.

With Mozilla opting to release new versions of its popular browser at light speed these days, it’s not surprising to see version 12 being released today – just 5 weeks after Firefox 11 dropped for Windows, Mac and Linux.

The Firefox browser by the Mozilla Corporation has been around since November 2004 and finds itself as one of the more favored, established web browsers. The browser is free and open-source which is managed on a day to day basis by Mozilla with recent estimates showing that it is the second most widely used internet browser, totaling approximately 25% of worldwide usage.

Mozilla yesterday announced that their Firefox web browser for Android has been updated with a more refined look along with updated tools for developers.
