Classic releases Netscape Navigator (versions 0.9–4.08) Netscape Navigator was Netscape's web browser from versions 1.0 to 4.8. The first
beta versions were released in 1994 and were called Mosaic and later Mosaic Netscape. Then, a legal challenge from the
National Center for Supercomputing Applications (makers of
NCSA Mosaic), which many of Netscape's founders used to develop, led to the name Netscape Navigator. The company's name also changed from Mosaic Communications Corporation to Netscape Communications Corporation. The browser was easily the most advanced available and so was an instant success, becoming a market leader while still in beta. But Netscape remained the most popular browser at that time. Netscape also released a Gold version of Navigator 3.0 that incorporated
WYSIWYG editing with
drag and drop between web editor and email components.
Netscape Communicator (versions 4.0–4.8) Netscape 4 addressed the problem of Netscape Navigator being used as both the name of the suite and the browser contained within it by renaming the suite to Netscape Communicator. After five preview releases in 1996–1997, Netscape released the final version of Netscape Communicator in June 1997. This version, more or less based on Netscape Navigator 3 Code, updated and added new features. The new suite was successful, despite increasing competition from
Internet Explorer (IE) 4.0 and problems with the outdated browser core. IE was slow and unstable on the Mac platform until version 4.5. Despite this, Apple entered into an agreement with Microsoft to make IE the default browser on new Mac OS installations, a further blow to Netscape's prestige. The Communicator suite was made up of Netscape Navigator,
Netscape Mail & Newsgroups, Netscape Address Book and
Netscape Composer (an HTML editor). On January 22, 1998,
Netscape Communications Corporation announced that all future versions of its software would be available free of charge and developed by an
open source community, Mozilla.
Netscape Communicator 5.0 was announced (codenamed "Gromit"). However, its release was greatly delayed, and meanwhile, there were newer versions of Internet Explorer, starting with
version 4. These had more features than the old Netscape version, including better support of
HTML 4,
CSS,
DOM, and
ECMAScript; eventually, the more advanced
Internet Explorer 5.0 became the market leader. In October 1998, Netscape Communicator 4.5 was released. It featured various functionality improvements, especially in the
Mail and Newsgroups component, but did not update the browser core, whose functionality was essentially identical to that of version 4.08. One month later,
Netscape Communications Corporation was bought by
AOL. In November, work on Netscape 5.0 was canceled in favor of developing a
completely new program from scratch.
Netscape 5 In 1998, an informal group called the
Mozilla Organization was formed and largely funded by Netscape (the vast majority of programmers working on the code were paid by Netscape) to coordinate the development of Netscape 5 (codenamed "Gromit"), which would be based on the Communicator source code. However, the aging Communicator code proved difficult to work with, and the decision was taken to scrap Netscape 5 and rewrite the source code.
Mozilla-based releases Netscape 6 (versions 6.0–6.2.3) When rewriting the source code, they had chosen to base it on the
Mozilla web browser, which, with a few additions and modifications, got Netscape 6 out. At first, it had performance and stability issues, but they were mitigated by subsequent updates, such as versions 6.1 and 6.2.
Netscape 7 (versions 7.0–7.2) Netscape 7.0 (based on Mozilla 1.0.1) was released in August 2002 as a direct continuation of Netscape 6 with very similar components. It picked up a few users, but was still very much a minority browser. It did, however, come with the popular
Radio@Netscape Internet radio client. AOL had decided to deactivate Mozilla's pop-up blocker functionality in Netscape 7.0, which created outrage in the community. AOL reversed the decision and allowed Netscape to reinstate the pop-up blocker for Netscape 7.01. Netscape also introduced a new AOL-free version (without the usual AOL add-ons) of the browser suite. Netscape 7.1 (codenamed "Buffy" and based on Mozilla 1.4) was released in June 2003. In 2003, AOL closed down its Netscape division and laid off or reassigned all of Netscape's employees. Mozilla.org continued, however, as the independent
Mozilla Foundation, taking on many of Netscape's ex-employees. AOL continued to develop Netscape in-house (with help from
Sun's Beijing development center
Mozilla Firefox-based releases Netscape Browser (version 8.0–8.1.3) Between 2005 and 2007, Netscape's releases became known as
Netscape Browser. AOL chose to base Netscape Browser on the relatively successful
Mozilla Firefox, a rewritten version of Mozilla produced by the Mozilla Foundation. This release is not a full Internet suite as before, but is solely a web browser. Other controversial decisions include the browser only being released for
Microsoft Windows and featuring both the
Gecko rendering engine of previous releases and the
Trident engine used in Internet Explorer, and switching between them based on a "compatibility list" that came with the browser. This effectively exposed users to the security vulnerabilities in both and resulted in a completely different user experience based on which site they were on. Examples are handling of right-to-left or bi-directional text, user interface widgets, bugs, and web standards violations in Trident, etc. On top of this, Netscape Browser 8 even broke Internet Explorer's ability to open XML files by damaging a
Windows Registry key, and would do so every time it was opened, even if the user fixed it manually. AOL's acquisition of Netscape Communications in November 1998 made it less of a surprise when the company laid off the Netscape team and outsourced development to Mercurial Communications. Netscape Browser 8.1.3 was released on April 2, 2007, and included general bug fixes identified in versions 8.0–8.1.2
Netscape Navigator (version 9.0) Netscape Navigator 9's features were said to include
newsfeed support and become more integrated with the Propeller Internet portal, alongside more enhanced methods of discussion, submission and voting on web pages. It also sees the browser return to multi-platform support across
Windows,
Linux and
Mac OS X. Like Netscape version 8.x, the new release was based upon the popular
Mozilla Firefox (version 2.0), and supposedly had full support of all Firefox
add-ons and
plugins, some of which Netscape was already providing. A beta of the program was first released on June 5, 2007. The final version was released on October 15, 2007. It was the first time the browser was produced in-house with its own programming staff since 2004.
End of development and support AOL officially announced The decision met mixed reactions from communities, with many arguing that the termination of product support is significantly belated. Internet security site
Security Watch stated that a trend of infrequent security updates for AOL's Netscape caused the browser to become a "security liability", specifically the 2005–2007 versions,
Netscape Browser 8. Asa Dotzler, one of
Firefox's original bug testers, greeted the news with "good riddance" in his blog post, but praised the various members of the Netscape team over the years for enabling the creation of Mozilla in 1998. Others protested and petitioned AOL to continue providing vital security fixes to unknowing or loyal users of its software, as well as protection of a well-known brand.
Mozilla Thunderbird-based releases Netscape Messenger 9 On June 11, 2007, Netscape announced Netscape Mercury, a standalone email and news client that was to accompany Navigator 9. Mercury was based on
Mozilla Thunderbird. The product was later renamed Netscape Messenger 9, and an alpha version was released. In December 2007, AOL announced it was canceling Netscape's development of Messenger 9 as well as Navigator 9. ==Product list==
