Mozilla Thunderbird Mozilla Thunderbird Mozilla Thunderbird is a free,[10] open source, cross-platform email, news, and chat client developed by the Mozilla Foundation. The project strategy was modeled after Mozilla Firefox, a project aimed at creating a web browser. On December 7, 2004, version 1.0 was released, and received more than 500,000 downloads in its first three days of release, and 1,000,000 in 10 days.[11][12] On July 6, 2012, Mozilla announced the company was dropping the priority of Thunderbird development because the continuous effort to extend Thunderbird's feature set was mostly fruitless. The new development model is based on Mozilla offering only "Extended Support Releases", which deliver security and maintenance updates, while allowing the community to take over the development of new features.[13][14] On November 25, 2014, Kent James of the Mozilla Foundation announced that more staff are required to be working full-time on Thunderbird so that the Foundation can release a stable and reliable product and make progress on features that have been frequently requested by the community. They have also set up a roadmap for the next major release, Thunderbird 38 due in May 2015. Features[edit] Thunderbird is an email, newsgroup, news feed, and chat (XMPP, IRC, Twitter) client. The vanilla version is not a personal information manager, although theMozilla Lightning extension adds PIM functionality. Additional features, if needed, are often available via other extensions. Message management[edit] Thunderbird can manage multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders ("virtual folders"), advanced message filtering, message grouping, and labels help manage and find messages. On Linux-based systems, system mail (movemail) accounts are supported. Junk filtering[edit] Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also understand classifications by server-based filters such as SpamAssassin.[16] Extensions and themes[edit] Extensions allow the addition of features through the installation of XPInstall modules (known as "XPI" or "zippy" installation) via the add-ons website that also features an update functionality to update the extensions. An example of a popular extension is Lightning, which adds calendar functionality to Thunderbird. Thunderbird supports a variety of themes for changing its overall look and feel. These packages of CSS and image files can be downloaded via the add-ons website at Mozilla Add-ons. Standards support[edit] Thunderbird supports POP and IMAP. It also supports LDAP address completion. The built- in RSS/Atom reader can also be used as a simple news aggregator. Thunderbird supports the S/MIME standard, extensions such as Enigmail add support for the OpenPGP standard. List of supported IMAP extensions: https://wiki.mozilla.org/MailNews:Supported_IMAP_extensions File formats supported[edit] Thunderbird provides mailbox format support using plugins, but this feature is not yet enabled due to related work in progress.[17] The mailbox formats supported as of July 2014 are: mbox – Unix mailbox format (one file holding many emails) maildir - known as maildir-lite (one file per email). Note: not yet stable, as of July 2014 Mozilla advise this format is still "too buggy for normal use"[18] Thunderbird also uses Mork and (since version 3) MozStorage (which is based on SQLite) for its internal database. Mork was due to be replaced with MozStorage in Thunderbird 3.0.,[19] but the 8.0 release still uses the Mork file format. The current version of SeaMonkey, version 2.14.1, also still uses Mork for its indexes for both POP and IMAP mail folders (at least). Limits and known issues[edit] The default mailbox format ("mbox") back-end allows a mailbox up to very large sizes (64 bit or file system limit). However if used in Local Folder mode, as is the case for POP3 email storage and other offline email stores, it has a usable limit of 4GB, with data corruption possible if this size is exceeded,[18] although Thunderbird tries to detect and prevent this. The limit was being actively worked on by developers in 2013 and remains open; it does not affect IMAP mail storage.[18] Compaction of near-4GB mailboxes is also potentially "very slow".[18] An issue also exists related to overly-long filenames in some cases, since Thunderbird must rely on the local computer for filing system limitations, while external email (IMAP especially) can have nested email folders with arbitrary length paths and filenames that cannot be stored under their intended paths and names.[18] Cross-platform support[edit] Thunderbird runs on a variety of platforms. Releases available on the primary distribution site support the following operating systems:[20][21] Linux Windows OS X Unofficial ports are available for: FreeBSD[22] OpenBSD[23] OpenSolaris OS/2 and eComStation[24][25] The source code is freely available and can be compiled to be run on a variety of other architectures and operating systems. Internationalization and localization[edit] Thunderbird does not yet support SMTPUTF8 (RFC 6531) or Email Address Internationalization. With contributors all over the world, the client is translated into at least 53 languages, but client's addresses are currently limited to ASCII local parts.[26] Security[edit] Thunderbird provides enterprise and government-grade security features such as SSL/TLS connections to IMAP and SMTP servers. It also offers native support for S/MIME secure email (digital signing and messageencryption using certificates). Any of these security features can take advantage of smartcards with the installation of additional extensions. Other security features may be added through extensions. For instance, Enigmail offers PGP signing, encryption, and decryption. Optional security protections also include disabling loading of remote images within messages, enabling only specific media types (sanitizer), and disabling JavaScript. The French military uses Thunderbird and contributes to its security features, which are claimed to match the requirements for NATO's closed messaging system.[27] History[edit] Main article: History of Mozilla Thunderbird This section is in a list format that may be better presented using prose. You can help by converting this section to prose, if appropriate. Editing help is available. (August 2014) Originally launched as Minotaur shortly after Phoenix (the original name for Mozilla Firefox), the project failed to gain momentum. With the success of the latter, however, demand increased for a mail client to go with it, and the work on Minotaur was revived under the new name of Thunderbird, and migrated to the new toolkit developed by the Firefox team. Significant work on Thunderbird restarted with the announcement that from version 1.5 onward, the main Mozilla suite would be designed around separate applications using this new toolkit. This contrasts with the previous all-in-one approach, allowing users to mix and match the Mozilla applications with alternatives. The original Mozilla Suite continues to be developed as SeaMonkey. On December 23, 2004, Project Lightning was announced which tightly integrated calendar functionality (scheduling, tasks, etc.) into Thunderbird, and which is now available as a downloadable extension. On October 11, 2006, Qualcomm and the Mozilla Foundation announced that "future versions of Eudora will be based upon the same technology platform as the open source Mozilla Thunderbird email program."[28]The project is code-named Penelope. In late 2006, Debian rebranded Thunderbird as Icedove due to trademark and copyright reasons. This was the second product to be rebranded.[10][29] On July 26, 2007, the Mozilla Foundation announced that Thunderbird would be developed by an independent organization, because the Mozilla Corporation (a subsidiary of the foundation) was focusing on Mozilla Firefox development.[30] On September 17, 2007, the Mozilla Foundation announced the funding of a new internet communications initiative with Dr. David Ascher of ActiveState. The purpose of this initiative was "to develop Internet communications software based on the Thunderbird product, code, and brand".[31] On February 19, 2008, Mozilla Messaging started operations as a subsidiary of the Mozilla Foundation responsible for the development of email and similar communications. Its initial focus was on the then upcoming version of Thunderbird 3. Alpha Preview releases of Thunderbird 3 were codenamed "Shredder". On April 4, 2011, Mozilla Messaging was merged into the Mozilla Labs group of the Mozilla Foundation.[32] On July 6, 2012, a confidential memo from Jb Piacentino, the Thunderbird Managing Director at Mozilla, was leaked and published to TechCrunch.[33] The memo indicated that Mozilla would be moving some of the team off the project and further development of new features would be left up to the community. The memo was slated for release on July 9, 2012. A subsequent article by the Mozilla Foundation Chair, Mitchell Baker, stated Mozilla's decision to make a transition of Thunderbird to a new release and governance model.[13][14] On November 25, 2014, Kent James of the Mozilla Foundation announced on the Mozilla blog that active contributors to Thunderbird gathered at the Mozilla office in Toronto and discussed the future of the application. They have decided that more staff are required to be working full-time on Thunderbird so that the Foundation can release a stable and reliable product and make progress on features that have been frequently requested by the community. They have also set up a roadmap for the next major release, Thunderbird 38 due in May 2015.[15] Releases Thunderbird development releases occur in three stages, called Beta, Earlybird, and Daily, which correspond to Firefox's Beta, Aurora, and Nightly stages. The release dates and Gecko versions are exactly the same as Firefox; for example, Firefox 7 and Thunderbird 7 were both released on September 27, 2011, and were both based on Gecko 7.0. .

    ........ Computer • History Museum Oral History of Winifred Mitchell Baker Interviewed by: Marc Weber Recorded: December 10, 2014 Mountain View, California CHM Reference number: X7311.2015 © 2015 Computer History Museum Oral History of Winifred Mitchell Baker Marc Weber: I'm Marc Weber of the Computer History Museum. And I'm here with Mitchell Baker, Chairwoman of Mozilla. Thank you so much for doing this interview. Winifred Mitchell Baker: Thanks, Marc. I'm happy to be here. The museum has been a bright spot for a long time, so I'm honored as well. Weber: Thank you. As am I. So start with a bit of your background. What is your full name? And when and where were you born? Baker: My full name is Winifred Mitchell Baker. My mom was a little eccentric though, and she never wanted me to use Winifred. So it's my first name. But in her mind, I was always Mitchell. So that's what I go by. And I was born in Berkeley in California in 1959. Weber: And tell me a little bit about your family and where you grew up. Baker: I grew up in Oakland, so the East Bay across from San Francisco. It borders Berkeley. My parents were born and raised on the East Coast and moved west, as people did in the '50s, where it seemed [like] starting a new life. They were each eccentric. And each had their own view of their world and really clear opinions. And I think some of that has rubbed off actually. Weber: So eccentric in what way? What did they do? Baker: Well, my dad was a classic entrepreneur.

  • Marcia Knous: My Name Is Marcia Knous
    Olivia Ryan: Can you just state your name? Marcia Knous: My name is Marcia Knous. OR: Just give us your general background. How did you come to work at Mozilla and what do you do for Mozilla now? MK: Basically, I started with Mozilla back in the Netscape days. I started working with Mozilla.org shortly after AOL acquired Netscape which I believe was in like the ’99- 2000 timeframe. I started working at Netscape and then in one capacity in HR shortly after I moved working with Mitchell as part of my shared responsibility, I worked for Mozilla.org and sustaining engineering to sustain the communicator legacy code so I supported them administratively. That’s basically what I did for Mozilla. I did a lot of I guess what you kind of call of blue activities where we have a process whereby people get access to our CVS repository so I was the gatekeeper for all the CVS forms and handle all the bugs that were related to CVS requests, that kind of thing. Right now at Mozilla, I do quality assurance and I run both our domestic online store as well as our international store where we sell all of our Mozilla gear. Tom Scheinfeldt: Are you working generally alone in small groups? In large groups? How do you relate to other people working on the project? MK: Well, it’s a rather interesting project. My capacity as a QA person, we basically relate with the community quite a bit because we have a very small internal QA organization.

  • Olivia Ryan: It's June 26 and We're Here with Mitchell Baker. Mitchell
    Mitchell BakerPart124K Page 1 Olivia Ryan: It’s June 26 and we’re here with Mitchell Baker. Mitchell, this is sort of a broad question, but when did you first sort of develop your interest in technology, and/or when did you begin working with computers? Mitchell Baker: Probably in 1990 when I moved to the Valley. I actually moved down here because I was interested in Asia and China, in particular, and I was a relatively new law school graduate, and I wanted to find some place that was actually doing things in Asia. So I moved to a law firm down here, which was a technology law firm that happened to do a lot in Japan and Taiwan. So that was really the start of it. Olivia Ryan: Okay. And how did you—what’s your role here at Mozilla and how did you come to work here? Mitchell Baker: I have a couple of different roles. The one that I’ve had the longest and I really treasure the most is the Chief Lizard Wrangler of the Mozilla project, which really means general manager but in a setting where there’s not necessarily an employment relationship. It’s a much more consensual set of people who choose to follow or choose to have someone be the leader. So that’s the first role. And then I’m also the CEO of the Mozilla Corporation. So that involves running the set of employees in the Corporation, as you might think. And I’m also on the board of the Corporation and its parent, the Foundation, as well.

  • Two Case Studies of Open Source Software Development: Apache and Mozilla
    Two Case Studies of Open Source Software Development: Apache and Mozilla AUDRIS MOCKUS Avaya Labs Research ROY T FIELDING Day Software and JAMES D HERBSLEB Carnegie Mellon University According to its proponents, open source style software development has the capacity to compete successfully, and perhaps in many cases displace, traditional commercial development methods. In order to begin investigating such claims, we examine data from two major open source projects, the Apache web server and the Mozilla browser. By using email archives of source code change history and problem reports we quantify aspects of developer participation, core team size, code ownership, productivity, defect density, and problem resolution intervals for these OSS projects. We develop several hypotheses by comparing the Apache project with several commercial projects. We then test and refine several of these hypotheses, based on an analysis of Mozilla data. We conclude with thoughts about the prospects for high-performance commercial/open source process hybrids. Categories and Subject Descriptors: D.2.9 [Software Engineering]— Life cycle, Productivity, Pro- gramming teams, Software process models, Software Quality assurance, Time estimation; D.2.8 [Software Engineering]— Process metrics, Product metrics; K.6.3 [Software Management]— Software development, Software maintenance, Software process General Terms: Management, Experimentation, Measurement, Human Factors Additional Key Words and Phrases: Open source software, defect density, repair interval, code ownership, Apache, Mozilla This work was done while A. Mockus and J. D. Herbsleb were members of software Production Research Department at Lucent Technologies’ Bell Laboratories. This article is a significant extension to the authors’ paper, “A case study of open source software development: the Apache server,” that appeared in the Proceedings of the 22nd International Con- ference on Software Engineering, Limerick, Ireland, June 2000 (ICSE 2000), 263-272.
