Testing FirefoxOS thanks to r2d2b2g

Many may have read the news that you can already try Firefox OS on the computer, all thanks to r2d2b2g (Ready to Deliver to Boot to Gecko), an extension that weighs around 60 MB and what can we get here.

Once we install the Extension, we are going to Tools »B2G Desktop, being able to use the ESC keys to go back or fn + right / fn + left (in the case of laptops) to go back to Home.


I don't have much to say about the interface. The way elements are scrolled and displayed is very similar to what other OS offer like Android, iOSEtc. ..

If I must admit that I really liked the finish of the icons, with its rounded appearance it is a bit different from what we are already used to seeing. I love how the message inbox looks and needless to say the browser.

Here are some screenshots of how it looks Firefox OS on Mi PC.

Performance and printing

Like version of Android that can be tested on the PC, Firefox OS it runs a little slow on some things, and sometimes the behavior is not what you expect. Sure, it is normal, first because it is not working in its natural habitat, and second, because r2d2b2g it is not yet a stable enough product.

Of course, being on a PC, we will not be able to see the options and functionalities that Firefox OS on a phone, but on the official website you can see some very interesting captures.

What really calls me from Firefox OS it is the technology that it uses for its operation. Unfortunately I have no knowledge yet of how to make any modification using HTML + JS, something that for me will be the main advantage of this system.

That yes, I predict an excellent future for Firefox OS And if, as they say, it can range from low-end terminals to the highest ranges, I'm sure it will be an excellent alternative to iOS, Android, BlackBerry OS y Windows Mobile.

    It looks very good, although it seems a bit heavy (At first glance), I hope this OS works perfectly on mobile phones, because it will be a very good alternative and a great step for Mozilla.

    A pity that it only works on 32-bit Linux (because at least it doesn't work for me). From the videos I have seen and other images, you can see the great work that the Mozilla team does.

      I also use Linux 64 (Arch). But to test it I installed bin32-firefox from the AUR. I don't know if you have any way to install 32-bit apps on a 64-bit Linux Chakra ...

        it would be a question of asking in the forum. I will do it in the next few hours. Thanks for the information.

    I have bad luck with Firefox OS: when I tried to install it from GitHub it did not exceed splash, and yesterday that I tried it with this extension (in a new profile just in case) it did not respond to the ESC and Super keys, so navigation was impossible. Also, unsurprisingly for such a large extension, it swallowed up all the RAM.

    It remains to wait to try again from git, or on a mobile when you have one where you can test it. 😛

    It seems like an excellent alternative, but I think that a new mobile operating system that appears in 2012 is a bit late to be an effective competition. You will only have a chance if you stand out a lot and offer things that others do not, because for the rest I do not see that it lasts long but proposes something new.

    Well, I think this could be the alternative for Linux users. The truth Android in terms of freedom falls very very short

      Open Firefox, and then drag this file (.xpi) from the file browser to any browser window, a new window will appear asking if you want to install the add-on.
