ⓘ Mozilla

Mozilla is a free software community founded in 1998 by members of Netscape. The Mozilla community uses, develops, spreads and supports Mozilla products, thereby promoting exclusively free software and open standards, with only minor exceptions. The community is supported institutionally by the not-for-profit Mozilla Foundation and its tax-paying subsidiary, the Mozilla Corporation.

Mozillas products include the Firefox web browser, Thunderbird e-mail client, Firefox OS mobile operating system, Bugzilla bug tracking system, Gecko layout engine, Pocket "read-it-later-online" service, and others.


1. History

On January 23, 1998, Netscape made two announcements: first, that Netscape Communicator would be free; second, that the source code would also be free. One day later Jamie Zawinski, from Netscape, registered mozilla.org. The project took its name, "Mozilla", after the original code name of the Netscape Navigator browser - a portmanteau of "Mosaic and Godzilla", and used to co-ordinate the development of the Mozilla Application Suite, the open-source version of Netscapes internet software, Netscape Communicator. Jamie Zawinski says he came up with the name "Mozilla" at a Netscape staff meeting. A small group of Netscape employees were tasked with coordination of the new community.

Originally, Mozilla aimed to be a technology provider for companies, such as Netscape, who would commercialize their open-source code. When AOL Netscapes parent company greatly reduced its involvement with Mozilla in July 2003, the Mozilla Foundation was designated the legal steward of the project. Soon after, Mozilla deprecated the Mozilla Suite in favor of creating independent applications for each function, primarily the Firefox web browser and the Thunderbird email client, and moved to supply them directly to the public.

Mozillas activities have since expanded to include Firefox on mobile platforms primarily Android, a mobile OS called Firefox OS, a web-based identity system called Mozilla Persona and a marketplace for HTML5 applications.

In a report released in November 2012, Mozilla reported that their total revenue for 2011 was $163 million, which was up 33% from $123 million in 2010. Mozilla noted that roughly 85% of their revenue comes from their contract with Google.

At the end of 2013, Mozilla announced a deal with Cisco Systems whereby Firefox would download and use a Cisco-provided binary build of an open-source codec to play the proprietary H.264 video format. As part of the deal, Cisco would pay any patent licensing fees associated with the binaries that it distributes. Mozillas CTO, Brendan Eich, acknowledged that this is "not a complete solution" and isnt "perfect". An employee in Mozillas video formats team, writing in an unofficial capacity, justified it by the need to maintain their large user base, which would be necessary in future battles for truly free video formats.

In December 2013, Mozilla announced funding for the development of non-free games through its Game Creator Challenge. However, even those games that may be released under a non-free software or open-source license must be made with open web technologies and Javascript as per the work criteria outlined in the announcement.

In January 2017 the company rebranded away from its dinosaur symbol in favor of a logo that includes a "://" character sequence from a URL, with the revamped logo: "moz://a".


1.1. History Eich CEO promotion controversy

On March 24, 2014, Mozilla promoted Brendan Eich to the role of CEO. This led to boycotts and protests from the LGBT community and its supporters, as Eich previously donated US$1.000 of his own money in 2008 in support of Californias Proposition 8, a California ballot proposition and state constitutional amendment in opposition to same-sex marriage. Eichs donation first became public knowledge in 2012, while he was Mozilla’s chief technical officer, leading to angry responses on Twitter - including the use of the hashtag "#wontworkwithbigots".

Protests also emerged in 2014 following the announcement of Eichs appointment as CEO of Mozilla. U.S. companies OkCupid and CREDO Mobile received media coverage for their objections, with the former asking its users to boycott the browser, while Credo amassed 50.000 signatures for a petition that called for Eichs resignation.

Due to the controversy, Eich voluntarily stepped down on April 3, 2014 and Mitchell Baker, executive chairwoman of Mozilla Corporation, posted a statement on the Mozilla blog: "We didnt move fast enough to engage with people once the controversy started. Mozilla believes both in equality and freedom of speech. Equality is necessary for meaningful speech. And you need free speech to fight for equality." Eichs resignation promoted a backlash as he seemed to have been forced out of the company.

OkCupid co-founder and CEO Sam Yagan had also donated $500 to Republican candidate Chris Cannon who proceeded to vote for multiple measures viewed as "anti-gay", including the banning of same-sex marriage. Yagan claims he did not know about Cannons stance on gay rights and that his contribution was due to the candidate being the ranking Republican participating in the House subcommittee that oversaw Internet and Intellectual Property matters.

Reader comments on articles that were published close to the events were divided between support for OkCupids actions and opposition to them. Supporters claimed the boycott was justified and saw OkCupids actions as a firm statement of opposition to intolerance towards the gay community. Opponents saw OkCupids actions as hypocritical, since Eich is also the inventor of JavaScript, which is still required to browse OkCupids website, and felt that users should not be punished for the actions of Mozilla and suspected that OkCupids actions were a publicity stunt.


2. Values

According to Mozillas manifesto, which outlines goals, principles, and a pledge, "The Mozilla project uses a community-based approach to create world-class open source software and to develop new types of collaborative activities". Mozillas manifesto mentions only its beliefs in regards to the Internet and Internet privacy, and has no mention of any political or social viewpoints.


According to the Mozilla Foundation:

The Mozilla Foundation pledges to support the Mozilla Manifesto in its activities. Specifically, we will:

  • Build and deliver great consumer products that support the Manifesto’s principles;
  • Use the Mozilla assets to keep the Internet an open platform;
  • Promote models for creating economic value for the public benefit; and
  • Build and enable open-source technologies and communities that support the Manifesto’s principles;
  • Promote the Mozilla Manifesto principles in public discourse and within the Internet industry.


3.1. Software Firefox

Firefox is a web browser, and is Mozillas flagship software product. It is available in both desktop and mobile versions. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. As of late 2015, Firefox had approximately 10-11% of worldwide usage share of web browsers, making it the 4th most-used web browser.

Firefox began as an experimental branch of the Mozilla codebase by Dave Hyatt, Joe Hewitt and Blake Ross. They believed the commercial requirements of Netscapes sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser. To combat what they saw as the Mozilla Suites software bloat, they created a stand-alone browser, with which they intended to replace the Mozilla Suite.

Firefox was originally named Phoenix but the name was changed so as to avoid trademark conflicts with Phoenix Technologies. The initially-announced replacement, Firebird, provoked objections from the Firebird project community. The current name, Firefox, was chosen on February 9, 2004.

It has been announced that Mozilla is going to launch a premium version of the Firefox browser by October 2019. The companys CEO, Chris Beard, has been quoted by The Next Web to say that "there is no plan to charge money for things that are now free. So we will roll out a subscription service and offer a premium level."


3.2. Software Firefox for mobile

Firefox for mobile codenamed Fennec is the build of the Mozilla Firefox web browser for devices such as smartphones and tablet computers.

Firefox for mobile uses the same Gecko layout engine as Mozilla Firefox. For example, version 1.0 used the same engine as Firefox 3.6, and the following release, 4.0, shared core code with Firefox 4.0. Its features include HTML5 support, Firefox Sync, add-ons support and tabbed browsing.

Firefox for mobile is currently available for Android 4.0.3 and above devices with an ARMv7 or x86 CPU.
