[edit] Web browser history

[edit] Web browsers by year

This is a table of personal computer web browsers by year of release of major version, in chronological order, with the approximate number of worldwide Internet users in millions. Note that Internet user data is related to the entire market, not the versions released in that year. The increased growth of the Internet in the 1990s and 2000s means that current browsers with small market shares, have more total users than the entire market early on. For example, 90% market share in 1997 would be roughly 60 million users, but by the start of 2007 9% market share would equate to over 90 million users.^[2]

[edit] Historical web browsers

This table focuses on OS and browsers of the 1990s and turn of the century. The year listed for a version is usually the year of the first official release, with an end year being end of development, project change, or relevant termination. Releases of OS and browser from the early 1990s to before 2001-2002 time frame are the current focus.

Many early browsers can be made to run on later OS (and later browsers on early OS in some cases), however, most of these situations are avoided in the table.Note, 'terminated' means the same as yes, it was supported in the final release but development stopped. Dropped means that major development has ended but development on other versions continued, while the reverse situation of added is not yet shown.

• ^  There are four different products which all carry the name Netscape: Netscape versions 1 to 4, properly called Netscape Navigator, was a browser based on the original Netscape engine. Netscape 4 also was available as an Internet suite, properly called Netscape Communicator. Netscape 6 and 7 was a new Internet suite based on the Gecko engine and the Mozilla Application Suite user interface. Netscape 8, properly called Netscape Browser, is a new browser based on Firefox that can use both the Gecko (Firefox) and Trident (Internet Explorer) engines. Netscape resumed use of the Navigator name from Netscape Navigator 9.0 beta 1. See Netscape for more info.

• ^  As of February 2007, at least Windows XP SP2 or Windows Server 2003 SP1 is required to install the latest version (v7) of Internet Explorer for Windows. Internet Explorer 6.0 SP1 is the last version that supports Windows 98, Windows Me, Windows NT 4.0 SP6a, and Windows 2000. Internet Explorer 7 is bundled with Windows Vista and Windows Server 2008
• ^  Safari is included with Mac OS X and the latest version is always available only from the OS install or OS updates.

[edit] Operating system support

The operating systems the browsers have been compiled to run on without emulation; for the given browser/OS combination, there are seven possibilities:

• No indicates that it does not exist or was never released.
• Partial indicates that while the browser works, it lacks important functionality or is extremely unstable compared to versions for other OSs (that is to say it has roughly alpha or pre-alpha quality). It is still being developed however.
• Beta indicates that while a version of the browser is fully functional and has been released, it is still in development (e.g. for stability).
• Yes indicates that the browser has been officially released in a fully functional, stable version.
• Dropped indicates that the latest stable version of the browser does not work on the operating system, although an older version is available that does. The number in parentheses is the last known stable version which was officially released for that OS.
• Terminated indicates that while the browser works (e.g. Internet Explorer for Mac), development has ceased and no new versions will be released; the number in parentheses is the last known stable version.
• Included indicates that the browser comes pre-packaged as part of or has been integrated into the operating system.

Please note that the list is not exhaustive, but rather reflects the most common OSs today (e.g. Netscape Navigator was also developed for OS/2 at a time when Mac OS X did not yet exist) but does not include the growing appliance segment (for example, the Opera web browser has gained a leading role for use in mobile phones, smartphones, the Nintendo DS and Wii, and Personal Digital Assistants, and is also used in Interactive televisions).

• ^  Internet Explorer is the only browser to natively support the Component Object Model (popularly known as ActiveX). Most other browsers use the NPAPI plugin architecture. ActiveX is more powerful than NPAPI in terms of the control it affords over the browser, but it is specific to Windows whereas NPAPI is cross-platform. There is a third-party plugin that adds partial ActiveX support, that is available for certain older versions of Mozilla Suite, Mozilla Firefox and Netscape Navigator. The default settings in earlier versions of Internet Explorer allowed the automatic download, installation, and running of new ActiveX controls with minimal user intervention - this made it possible to use ActiveX on web pages to install viruses, spyware, etc. onto a user's computer.
• ^  Spell checking can be added by installing an add-on like ieSpell.
• ^  Lynx is able to edit text with an external editor, which can provide spell checking.
• ^  Internet Explorer can handle per-site settings for cookies. Furthermore you can specify "trusted" and "untrusted" sites and assign pre-set rights to both categories.
• ^  Mozilla based browsers like Firefox, SeaMonkey and Flock can handle per-site settings for cookies. For more settings you need an add-on, for example NoScript.
• ^  For the download manager kdenetwork needs to be installed.
• ^  On Linux and Windows, Spell checking requires GNU Aspell to be installed.
• ^  Opera can auto-complete forms with your personal information and website usernames.

Browser	Tabbed browsing	Pop-up blocking	Incremental finding	Ad filtering	Page zooming †

• ^  Page zooming is different from text resizing, as it resizes not only characters, but also multimedia objects and web page layout.  Not yet available in current Gecko (1.8, e.g. Mozilla Firefox 1.x/2.x: fixed by 'Web Developer' extension), but will be in Gecko 1.9 (2007, e.g. Mozilla Firefox 3)[2].
• ^  Epiphany supports AdBlock as an official extension, in the epiphany-extensions package.
• ^  Opera 9 introduced a content blocker for webpages. [3]. Earlier releases support wildcard protocol/domain/path and filetype blocking using a filter.ini [4] file. More advanced Ad filtering for Opera can also be done with external software [5].
• ^  Tabbed browsing turned off by default in Safari 2.
• ^  Does not allow selective blocking of pop-ups—can only block all pop-ups, or none.
• ^  Page zooming only supported in the iPhone version of Safari.
• ^  Several extensions are available through the Windows Marketplace [6], including "Inline Search for Internet Explorer"[7].

• ^  CSS 2, a W3C recommendation since 1998, is the current stable version of CSS, nevertheless, CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition of the height/width of absolutely positioned elements, more influence for HTML's "style" attribute and a new calculation of the 'clip' property), and adds a few highly requested features which have already been widely implemented. CSS 2.1 is derived from and is intended to replace CSS 2. Conformance criteria are detailed at at the W3C website. (CSS 3 is only in draft status at present.) For more detailed information please see comparison of layout engines (CSS).
• ^  LINK as a navigational aid, as distinct from non-navigational uses of LINK.
• ^  Not in standard install, but provided by extension.[16][17]
• ^  XHTML is based on HTML but is an application of XML, which means that XHTML must be stricter than equivalent HTML code. XHTML is meant to be read by an XML parser but for backward compatibility reasons can also be parsed as HTML; this table only notes the browsers that are able to parse XHTML as XML. For more detailed information please see comparison of layout engines (XHTML).
• ^  Dillo displays frames as links that the user can click on.
• ^  Internet Explorer 7 only
• ^  Available with the MathPlayer plugin.
• ^  XForms is supported experimentally in nightly builds dated after January 28, 2005 [18]. Requires installation of an extension.
• ^  RSS and ATOM feed autodetection in Konqueror depends on the aKregator package which is installed with kdepim.
• ^  It is possible to use CSS to partially style MathML in Opera (see here for more). Since Opera 9.0 Technical Preview 2 (Opera 9TP2) it is also possible to use a user javascript method to support MathML (see here).
• ^  RSS and ATOM feed autodetection in Epiphany depends on the Newsfeed extension which is included with Epiphany-extensions.
• ^  Web Forms 2.0 can be emulated in IE using DHTML behaviours, available from SourceForge.
• ^  Web Forms 2.0 functionality is currently being added to Gecko, there should be at least partial support for Gecko 1.9 (Firefox 3.0). See bug #344614.
• ^  XHTML1.1 includes RUBY (see [19]) which is not supported. There exists add-on for adding RUBY support. [20]

Browser	JPEG	JPEG 2000	GIF	PNG	APNG	MNG	TIFF †	SVG †	PDF †	2D Canvas

• ^  Mozilla Firefox's support for APNG was introduced in Gran Paradiso Alpha 3 [23]. Current stable releases do not contain support for APNG. More Information.
• ^  Internet Explorer does not support progressive display of progressive JPEG.
• ^  Internet Explorer supports PNG images but is unable to correctly display images with gamma correction or color correction. Versions of Internet Explorer prior to version 7 are unable to correctly display images with alpha channel (for transparency) without additional coding [24].
• ^  Support of MNG/JNG was dropped since June 6, 2003 [25] [26]. There are unofficial builds with MNG/JNG called Mngzilla [27].
• ^  Most browsers support TIFF by using a plugin installed by the user.
• ^  SVG here refers to SVG 1.1 Full. There are also two simplified profiles known as SVG 1.1 Tiny and SVG 1.1 Basic, which are intended for user agents with limited capabilities.
• ^  KDE has developed its own SVG plugin for Konqueror, known as KSVG [28]. KSVG1 development has ended, but work on the next-generation KDOM-based KSVG2 has been very active [29]. KSVG2 is slated to be moved into the core KDE [30] meaning at some point KSVG2 should become part of Konqueror.
• ^  Firefox and SeaMonkey partially support SVG 1.1 Full. Modules that are implemented or not implemented and details of their implementation: [31].
• ^  Opera's support for APNG was introduced in Opera 9.5 Alpha [32]. Current stable releases do not contain support for APNG.
• ^  Opera supports SVG 1.1 Basic. [33]
• ^  Safari supports JPEG2000 through QuickTime plugin, which is an optional software bundle for Safari installation on Windows, and an integrated component in Mac OS.
• ^  Safari 3 is able to render SVG documents, but not fully [34].
• ^  Most browsers support PDF by installing an Adobe plugin which takes over the browser window. Listed here are browsers which also support inline PDFs within other hypertext documents (such as within HTML's <img/> tag). Note that PDF (in strictly speaking) is not an image format, but a scriptable rich text document format that can contain different types of multimedia content, including vector and bitmap graphics, audio, video, forms, intra- and inter-document hypertext links and a hierarchical contents listing. The format is also the native display format under Mac OS X.
• ^  Inline PDF viewing in Konqueror requires KPDF which is included in kdegraphics.
• ^  Internet Explorer can be made to emulate canvas using the script provided by Google.
• ^  Support for these features depends on the version of the Gecko rendering engine that Epiphany was built with.
• ^  With the addition of the new Cairo version in Gecko 1.9 it will be natively possible to save pages to PDFs but not read them. Whether this feature will be included in Firefox 3.0 or later has yet to be specified it is however possible with the new Cairo backend.

[edit] Internationalization
