Firefox OS Images (ROMs) Download Centre – All in One


Since the launch way back in 2013 Mozilla led Firefox OS has almost has 20 smartphones running various versions of the smartphone operating system. Among the first set of devices ZTE Open and Alcatel OneTouch Fire were launched with Firefox OS v1.0. For the end user’s point of view, there isn’t much software updates since the launch of those two. But in these three years Firefox OS has changed a lot. Just like Android OS, there are few independent developers who works day and night to build custom builds (read Custom ROMs). Devices like Geeksphone Keon, Peak, Revolution, Alcatel and ZTE devices has among the favourites with the developers. They build ROMs for the devices and publish on their blogs, but if you don’t know them or their blogs, it’s really hard to know that a new version of the custom ROM is available. On this post we will try to create a list (Firefox OS Download Centre) with all of them together to give you an one stop solution.

Where are the announced Firefox OS Devices?


After launching in Spain, Firefox OS travels through Eastern Europe, most of the Latin American countries, few Asian nations, lets not forget Australia (recently Vanuatu) before entering African continent. Currently we have around 20 Smartphones available in the market and there are few coming up (later this year and the next), but what about those which are announced, showcased and then we don’t have any clue of them till now.

Today I’m going to give you few of those Firefox OS devices which were officially announced by the manufactures but not yet released.

1) Yezz Foxy 4 and Yezz Foxy 3.5:

Yezz foxy series with Firefox OS

Announced way back at CES 2015, these two Firefox OS devices were announced by the company called Yezz Mobile, but till now none of the devices are available in the market. On Yezz 4 you will get 4″ Screen, 1GHz single core processor, 4GB of ROM, 512MB of RAM, Dual SIM, memory card support upto 64GB (that’s awesome dude!), 2MP primary camera along with VGA front Cam. On the other hand Yezz Foxy 3.5 has exact same configuration apart from the screen size which is 3.5″. We don’t know when and in which markets Yezz will launch their Foxy series of Smartphones. If you have any news about it do share with us.

Possibly the best configured Smartphone powered by Firefox OS when announced. It has 4.5″ qHD screen with 1.2GHz Quad Core Processor, 4GB ROM, 1GB RAM, 8MP primary Camera along with 2MP front shooter. It’s one of the first LTE devices announced with Firefox OS.

In which markets Smart Feature Phone will be launching first?


Mozilla made it official few days ago that the much awaited Smart Feature Phones are indeed exist and soon become available in market. But the big questions are – Which brand is going to launch the device and in which market?

We tried our best to know, but it seems Mozilla and the manufactures are making it super tight :D

Till now all we know is Verizon Wireless, LG U+ and KDDI are the top telecom providers to distribute the device, but the main interesting part we came to know that the first market is USA with a Flip Phone (clamshell).

So it’s quite final that Verizon Wireless is the first Telecom operator to bring Firefox OS in the United States with a Flip Phone powered by Firefox OS. We can also easily predicts that the next major manufacturer is LG along with KDDI and LG U+ for Japan and South Korean market.

If you know anything about the Smart Feature Phone, do let us know in the comment section below.

Interview: Mariot Tsitoara of Mozilla Madagascar talks about Firefox OS in Africa


Few months back Firefox OS reaches Africa, one of the most potential market till now due to its vast land scape and population. By August this week (2015) more than 10 African countries have Firefox OS up and running. So how good actually the Fox is jumping on African soil? Well, there is hardly any official statement we have till now, so we though to reach the key persons of Mozilla communities in Africa to know the actual situation. So from this week, on a weekly basis we will publish an interview with one Mozilla Community member where Firefox OS is available. Starting with Mariot from Mozilla Madagascar who is an evangelist, translator and coder for the Malagasy Mozilla Community. Let’s have a look how good is Firefox OS in Africa!



So without further ado, here is what Mariot has to say:

FFOSG: Introduce yourself to the world. (brief bio, Moz member since, role and designation in your country’s Mozilla community)

I’m Mariot Tsitoara, 22 and Mozilla member since January 2014. I’m an evangelist, translator and coder for the Malagasy Mozilla Community.

FFOSG: What’s your role before, during and post Orange Klif launch in your country?

Before the Orange Klif launch, I was a Mozilla enthusiast and I was active mainly on social media.

During the launch, I worked with the Orange marketing team and we went to universities around the country to present the Klif. They advertised the phone and I talked about Firefox OS and Mozilla.

After the initial launch, we are now working on a new strategy to boost Klif sales. I am helping the Orange team to host a Firefox OS app development challenge to promote the OS and help in the creation of more local apps.

FFOSG: what are the key areas mozilla working in your country.

In Madagascar, we mostly know Mozilla as the company behind the Firefox browser. With the launch of Firefox OS, we got to know Mozilla better and understood its goal. As a developing country, the gift that Mozilla offers is very welcome here!

I think that would be Ubuntu phone because they are also open source and constructed around more or less the same values as Firefox OS.

FFOSG: What’s the current scenario of telecom industry in your country and what changes you are expecting after Orange Klif launch in your country.

The telecom industry in Madagascar is a really competitive one. That leads to very impressive marketing strategies and we always get new technologies. After the launch, I’m expecting a really good buzz for Firefox OS because every telecom company wants to get a hold of it to attract new consumers.

FFOSG: What are the major hurdles you are facing while introducing FirefoxOS to the local community, what methods you are applying to overcome it.

The major hurdle is that people want the same OSes that their peers. They don’t really trust new OSes because they are worried about compatibility issues and lack of performance.

To overcome it, I show them all the most popular apps that are available for Firefox OS. It’s necessary to really show them the apps and the phone and not just talk about them.

FFOSG: The buzz is strong that in next few years Firefox OS will become world third largest popular Smartphone OS, what’s your take on this.

Most Firefox OS users are from Africa. Since we have such a big target audience, I think that we can always get new users by ameliorating the features. I sincerely think that we have the potential to launch Firefox OS at least at the second place.

FFOSG: Smart feature phones are coming with Firefox OS, give our readers some insights about it.

Indeed, there are a lot of smart feature phone coming out lately. They are attractive for the consumers because of their prices. The major problem with them is that they offer little freedom of choice for the users and they rely only on third party software, which limits the number of apps available.

FFOSG: Which type of Smart device will do good in your country (Smartphone or Smart feature phones) powered by FirefoxOS? Why?

I think it’s the Smartphone because it becomes so popular here. Firefox OS is a great first phone because it has all the necessary features and it adapt well with everybody. And it has the advantage of being so affordable while being so useful. Even if teens are a little bit unimpressed with it, Firefox OS is a great leap forward in the Open Web.

FFOSG: In next three years where will you see the position of FirefoxOS in the Smartphone market?

As I said earlier, I think that Firefox OS will be a very popular choice in Africa because of its price and features. For the worldwide market, we will have a lot of work to do!

FFOSG: Among the new born Smartphone OSes which according to you will be the toughest competition to FirefoxOS? Why?

I think that would be Ubuntu phone because they are also open source and constructed around more or less the same values as Firefox OS. And obviously, Android is a very tough competition as it’s currently the most popular.

FFOSG: Why do you think consumers should pick Firefox OS instead of other current smartphone OSes?

Consumers should pick Firefox OS because it has all that they need, at a small price. It offers everything that they need in a smartphone OS and offers them an open door to the web.

FFOSG: Any messages you want to give to our readers?

Mozilla believes in an Open Web and Firefox OS is the right tool to achieve that goal. With this OS, we make the world better by giving more freedom and privacy. So we need to push Firefox OS further and accomplish the manifesto in the meantime.

Hope you enjoyed the interview, next week we will bring you the interview of Ganesh (Mozilla Mauritius) and give you the complete scenario of Firefox OS in Africa (Mauritius).
