Backing up your contacts on FirefoxOS

25 July, 2013 § 21 Comments

I’ve been helping beta test B2G and subsequently FirefoxOS since October 2012.  Once in a while I’ve come across a bug that requires me to reset the phone back to its factory state. Unfortunately at this early stage there isn’t a built-in way to back up your data from a FirefoxOS phone. I’m sure it’s on a roadmap, but as with all v1 products you have to make some tough calls when it comes to feature prioritization.

This tutorial provides a step-by-step walk through of how to backup and restore your contacts on a B2G or FirefoxOS phone. It’s not supported so it may stop working in the future, but for now it works 🙂

To complete this tutorial you’ll need a B2G/FirefoxOS phone, a USB cable to connect your phone to your computer, and the Android Debug Bridge installed (referred to as `adb` later in the tutorial).

1. Start up your FirefoxOS phone and go to Settings.


2. Go to Device Information


3. Go to More Information


4. Go to Developer


5. Enable “Remote Debugging”. This will allow you to use ADB to pull data off of the phone.


6. Connect your phone to the computer using the USB cable.

7. In your console, type `adb devices` to check that the phone has connected properly. You should see your phone listed as an attached device. At this point you can now use `adb shell` to browse through the system files on the phone.

8. Type `adb pull /data/local/indexedDB/chrome/3406066227csotncta.sqlite .` This will pull the contacts IndexedDB database off of your phone and in to your local working directory. If you are curious about the contents of the database, you can install the IndexedDB Browser add-on for Firefox which will let you open up the database.


And you are now done with backing up your contacts. If you need to reset your phone in the future, you can just follow these steps again but replace step 8 with the following: `adb push 3406066227csotncta.sqlite /data/local/indexedDB/chrome/3406066227csotncta.sqlite`. This will push your backed-up contacts database back on to the device.

Firefox OS – The Web is the Platform

14 May, 2013 § 3 Comments

This past Monday I gave a presentation at the Mobile Monday Detroit meeting about Firefox OS. Thanks to some great screen recording software by TechSmith, I also recorded it 🙂

I’ve also made the slides available online for those who just want to read (press ‘s’ on your keyboard to see my speaker notes, you may have to allow pop-ups).

Mobile Monday Detroit is a monthly meetup that gets people together to talk about activity in the mobile space. Many topics cover Android and iOS, so it was really cool to snag a spot on the podium and give a talk about one of the ‘alternative’ operating systems. Also presenting this week was Randy Nunez from Ford who gave a talk about the various open source mobile operating systems and Chris Peplin from Ford who talked about the Open XC API for cars that Ford is working on.

If you live in southeast Michigan you should try to make it out to one of the meetings. More information can be found at the Mobile Monday Detroit Meetup page.

Firefox OS at Mobile Monday Detroit

jared-weinIf you haven’t heard about Firefox OS before, or would like to learn more about it, you should come to this month’s Mobile Monday Detroit. I’ll be presenting at the meeting about Mozilla’s motivations for Firefox OS, how we’re opening up mobile hardware, and roadmap for the future.

mobile-mondayIt has been estimated that in the next 10 years, five billion people will gain access to the internet. Many of these people will be accessing the internet using mobile connection exclusively.

One of the main goals of Firefox OS is to provide a device to people that brings with it the full web as compared to the limited subset of the web that is currently accessible on more basic feature phones. This also means providing web applications better access to hardware, so application developers can provide rich environments comparable to that of other mobile phone operating systems.

As we build these hardware APIs, we have been working very hard to standardize them and push for other browsers to adopt them. You can follow along with the progress of the WebAPI project by visiting our wiki. All of the FirefoxOS roadmaps, feature lists, etc can all be viewed online. This project really defines openness 🙂

The event will start at 5:30pm and run until 8pm. Food and drinks will be provided. Please RSVP (it’s free!) if you plan on attending so the organizers will have a good idea of how much food to order.

Randy Nunez from Ford will also provide information on a variety of additional open source mobile OS platforms that are catching the attention of the developer community.

Come learn about FirefoxOS at MobiDevDay Detroit

10 March, 2013 § Leave a comment

I’m excited to announce that I will be presenting at MobiDevDay Detroit on May 4th on the topic of Firefox OS.

FirefoxOS is Mozilla’s new mobile operating system, based entirely on web technology. FirefoxOS will bring full device capabilities to the web stack, allowing web developers to create immersive experiences in a cross-platform and device agnostic manner.

This talk will briefly cover the motivations of FirefoxOS and then dive in to the new technology and APIs that are being opened up to developers who are looking to create apps for FirefoxOS.

MobiDevDay Detroit was the first conference of its kind. Now in its third year, MobiDevDay is dedicated to bringing the world of Mobile to Michigan’s Software Developer Community. We hope to grow MobiDevDay Detroit into the most important polyglot Mobile Developer conference in the world.

MobiDevDay Detroit 2013 will be held at the Cobo Conference Center on May 4th.

Breakfast, Lunch and Free Parking will be provided.

Register today for the conference before it sells out. I’ll share more details about my talk as the date gets closer.
