Firefox OS is one of Mozilla’s revolutionary project that still is on developing process. Many developers, QA Engineers are still working to bring more satisfactory features and facilities toward open-source lover. But unfortunately, MOST of the developers don’t have the Firefox OS device to participate on developing. So in order to do so, the community has figure out another way to make available to contribute on this open-source project.

How to Download Firefox builds form Mozilla HTTP Server

Hello Everyone,

Today we are going to learn how to download firefox builds from Mozilla HTTP Server.

Those who are new to Mozilla QA(Quality Assurance) they have to know how to download the correct build. So lets started with a bug from Bugzilla.

That’s a bug report looks like. Now we are studying this case as a demo. Don’t worry about the meaning of some terms like whiteboard, Target Milestone, Blocks etc. Now have a look on Reported & Platform terms.

Capture4The platform section indicates the Operating System and its architectural bit. In this case the OS could be anything (windows, linux etc) and it’s system type 64/32 bit.

Capture3The Reported Section indicates the date and time when the bug has been submitted to bugzilla. In this case the date is 25th of March, 2015. So to examine the bug we have to download a 32/86 bit build of that date. Here we are downloading a Firefox Nightly Build because in general we are verifying bugs in nightly build.

Mozilla has 4 Firefox Builds for desktop.


This is Mozilla HTTP server link. Now go to this link.


Now go to the nightly folder. Then go to the folder named 2015.


Then go to the folder named 03. (Here number indicates the month).


Then find the exact date folder. In our case it will be 2015-03-25-mozilla-central. (Note: Central=Nightly & Aurora=Developer Edition).


Go to the folder and search for the OS which you are currently worked on. I have Windows based operating system, so for this particular case I choose



Extract the .zip file and you are ready to go.

Happy contributing :)

Building and Maintaining a Healthy Community

Screenshot from 2015-10-20 12:51:42

A community is a social unit of any size that shares common values. Although embodied or face-to-face communities are usually small, larger or more extended communities such as a national community, international community and virtual community are also studied. In human communities, intent, belief, resources, preferences, needs, risks, and a number of other conditions may be present and common, affecting the identity of the participants and their degree of cohesiveness.the main realistic meaning of a community is a group of people who connect well together socially, mentally or sometimes economically

Since the advent of the Internet, the concept of community has less geographical limitation, as people can now gather virtually in an online community and share common interests regardless of physical location. Prior to the Internet, virtual communities (like social or academic organizations) were far more limited by the constraints of available communication and transportation technologies.

Introduction to Bug and Bugzilla

What is a Bugzilla?


Bugzilla is a web-based general-purpose bugtracker and testing tool originally developed and used by the Mozilla project, and licensed under the Mozilla Public License.

Released as open-source software by Netscape Communications in 1998, it has been adopted by a variety of organizations for use as a bug tracking system for both free and open-source software and proprietary projects and products.

The UserInterface of Bugzilla Looks Like this,

Mechanism To Be Followed for Bugs

Bug Verfication

Bug verification is done to verify that bugs are properly fixed and to check that the fixes don’t yield any new issues. This is a very important part of the QA work and one of the more challenging areas of community involvement.

Triaging Bugs

Bug Triaging is the process of moving bugs logically from state to state, so they get resolved in an efficient and easy-to-comprehend manner. In Mozilla, QA must not only test and then file their own bugs, but must also help harness the incoming flow of community bugs for valid problems.

Confirming Unconfirmed Bugs

Bugs from new bug reporters will initially have the status UNCONFIRMED. To move a bug from UNCONFIRMED to NEW, we need your help to verify that the bug is valid. A bug can be moved from UNCONFIRMED to NEW
