Frequently asked questions

What is B2G OS?

The Boot to Gecko (B2G) project was started in 2011 to build a complete, standalone operating system for the Open Web. B2G is a community maintained open source project based on the Linux kernel and Gecko rendering engine and has been used as the basis of commercial Firefox OS smartphone and smart TV products.

In December 2015, the Mozilla Corporation announced it was shifting its focus away from smartphones to other types of connected devices. Since then a transition project has been underway to modernize B2G and create a leaner platform on which to build smart TVs and other potential connected devices products in the future. As part of this transition, Mozilla's community of volunteers is taking ownership over the smartphone-specific parts of B2G, which makes Mozilla employees focus on their efforts elsewhere.

The transition project aims to replace Mozilla's legacy app runtime with new standards-based web apps and move the core B2G system closer to the architecture of the Firefox web browser. This will reduce complexity and maintenance costs and create a platform for the future based on emerging web standards.

Where is Mozilla going?

As mentioned earlier on Mozilla Corporation announced, part of the team will be focused on connected devices, and Mozilla's community of volunteers is taking ownership over the B2G OS. Mozilla is a well-known non-profit and most trusted company in the Internet world, it is thus important that we focus on promoting openness accessibility, privacy and security in this new phase and on pivoting to Connected Devices has becomes a path forward as we seen the tremendous devices forecast of Internet of Things (IoT) by 2020.

Why Do We Need Your Help?

Maintaining an operating system is a big project. A large community of volunteers is needed if we want to keep B2G running on the smartphone form factors. There are many contributing ways, such as building and testing the OS, filing and fixing bugs, developing new features, porting to new devices, helping with documentation and localization, and even just using and talking about the B2G project.

Help is already needed on the transition project to get core system features working, to port smartphone apps to the new architecture, and to document everything which has changed. Once the transition is complete, we hope to build an even bigger community of contributors to help B2G moving forward.

If you're interested in the challenge of maintaining a complete and standalone operating system for the Open Web, then we want to hear from you! B2G is made by the community for the community and we need your help.

What does the “chrome” mean?

In a browser, the chrome is any visible aspect of a browser aside from the webpages themselves (e.g., toolbars, menu bar, tabs). This should not to be confused with the Google Chrome browser.

When will you officially end developing Firefox OS?

Despite most of the Mozilla employees will be focusing on Connected Devices, the development of B2G OS will never end. May 31st is officially set to be smartphone transition completed.

What will happen to Firefox OS staff?

Mozilla employees will continue to work on other product initiatives across Connected Devices and other Mozilla teams.

"I'm a web (HTML/CSS/JavaScript) developer, how can I help?"

By porting a Gaia smartphone app: figure out ways to get it working as a web app (or turn it into chrome)

• The changes on Gaia for the transition project
• See a list of the smartphone apps which need transitioning to web apps …
• … and the GitHub repository
• about differences between apps

"How can I install Vidyo on Ubuntu 16.04 or Debian 8?"

Vidyo is not installable on Ubuntu 16.04 and Debian 8, this is because the package from the Vidyo website has a bogus dependency listed in their install manifest (libqt4-gui instead of libqtgui4).

If you want to install Vidyo, try this package then manually install libqtwebkit4 with apt install libqtwebkit4

Otherwise, try to use equivs tool. To do that, follow this guide.
