Usage share of web browsers on Wikimedia in September 2012

1. Chromium, on which Google Chrome is based, is open source; the features Google adds to Chrome (such as H.264 and ACC decoding, built-in Adobe Flash, and an auto-updater system, among other things) are closed-source. See Chromium (web browser) § Differences from Google Chrome and Google Chrome's Terms of Service for more info.
2. There are five 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, was a distinct browser based on Firefox that could use either the Gecko (Firefox) or Trident (Internet Explorer) engine. Netscape resumed use of the Navigator name from Netscape Navigator 9.0 beta 1. See Netscape for more info.

Operating system support

Browsers are compiled to run on certain operating systems, without emulation.

This list is not exhaustive, but rather reflects the most common OSes today (e.g. Netscape Navigator was also developed for OS/2 at a time when OS X did not 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). Both the web browser and OS means most recent version, example: Windows 8 with Internet Explorer 10.

1. On Mac systems, gestures are available systemwide via multitouch sensing on trackpads and mice.
2. On OS X, text-to speech and speech recognition are available systemwide and is available from menu in native Cocoa browsers.
3. Google Chrome can be given these features using extensions like smooth gestures, speechify and voice control for google chrome.
4. ELinks 0.12 supports spatial navigation.
5. Mouse gesture support can be added by installing extensions like All-in-One Gestures (Firefox-only) and Mouse Gestures .
6. Internet Explorer 8 supports caret browsing.
7. Mouse gesture support is available via plug-ins, i.e. Mouse Gestures for Internet Explorer or Easy Go Back.
8. TTS in Internet Explorer is available through the operating system Speech API. For TTS, SAPI takes text as input and uses the TTS engine to output that text as spoken audio. This is the same technology used by the Windows accessibility tool, Narrator. SAPI and an English TTS engine have been embedded in all Windows operating systems since the release of Windows XP.
9. Internet Explorer can be controlled by applications which use the operating system Speech API. A built-in application called Windows Speech Recognition ships with Windows Vista and later client versions.
10. Mouse gesture support is available system-wide in KDE
11. Text-to speech support depends on the kttsd application in the kdeaccessibility package
12. Doug Turner, the Minimo lead developer, has introduced spatial navigation to some special Firefox builds . It may build as a default part of Firefox .
13. Firefox works with a number of screen readers such as JAWS (screen reader) and Microsoft Speech API through extensions.
14. opera : a sort of caret navigation can be enabled by a button or a shortcut (Archive copy at the Wayback Machine)
15. Available as of this commit.
16. Supports as of v1.7.0: https://github.com/QupZilla/qupzilla/issues/458
17. Available as a Mouse Gestures plugin which is disabled by default, but it is part of default installation.
18. On OS X systems, caret navigation (called "Full Keyboard Access") can be enabled systemwide.
19. Mouse gesture support can be added by installing extensions like Mouse Gestures Suite (Seamonkey-only) .
20. Web supports mouse gestures as an extension from the official extensions package.

Acid scores

The Acid tests are online test suites to determine aspects of standards compliance, to expose web page rendering flaws, and to rate the performance of browsers. Upon each test's release, they are designed so that no existing browser can pass without further development. In order for a browser to pass any Acid test, the latest public release of the browser (not an alpha, beta, release candidate, or other version under development or testing procedures) must meet the requirements shown below. In addition, the browser should be tested upon completion of installation, with no add-ons installed (some browsers make this easy by providing a "safe mode" option) and all the factory settings (no options have been changed from their defaults).

Acid1:

• Final rendering looks exactly like the rendering provided by the Acid tests website.
• Text can be highlighted and radio buttons can be selected.

Acid2:

• Final rendering looks exactly like the rendering provided by the Acid tests website.
• Smiley's nose turns blue when hovered over.

Acid3:

• Final rendering looks exactly like the rendering provided by the Acid tests website.
• Test does not report failed tests or abnormal delays (leftclick letter "A" to obtain a report)

HTML5 support

The specifications for HTML5 are still under development, but many current browsers already support many of the new features in the draft specifications. An HTML5 test suite is also under development that, while it does not test all of the new features nor the functionality of those it does detect, rates browsers' support. New tests are expected to be added to the suite as time goes by.^[69]

Browser	HTML5test score[70]
Apple Safari 9.0	400/555
Google Chrome 44	526/555
Internet Explorer 11	336/555
K-Meleon 75	406/555[71]
Microsoft Edge 13	453/555
Mozilla Firefox 40	467/555
Opera 31	525/555

As new tests are added, bogus ones removed, etc., new versions of html5test.com become available as preliminary beta or even alpha versions. These are great to test development versions (e.g. nightly builds) of web browsers, but their results should be taken with a grain of salt. Especially when considering that some browsers have experimental features built in which may be switched off by default.

1. 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 the W3C website. (CSS 3 is only in draft status at present.) For more detailed information please see comparison of layout engines (CSS).
2. Frames and frame sets are obsolete and non-conforming in HTML5. They should not be used by authors.
3. LINK as a navigational aid, as distinct from non-navigational uses of LINK.
4. 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).
5. Presentation mode is the ability to read styles targeted to the CSS projection media type. As of Media Queries Level 4, the projection media type is deprecated.
6. Available with the MathPlayer plugin.
7. Dillo displays frames as links that the user can click on.
8. S5 is a CSS/JavaScript alternative for browsers that do not support a presentation mode.
9. Microsoft claims Internet Explorer 8 has full CSS2.1 support,^[74] however independent testing revealed several bugs.^[75]
10. Not in standard install, but provided by extension.
11. Available with the FormsPlayer plugin and several other plugins.
12. Web Forms 2.0 can be emulated in IE using DHTML behaviours, available from SourceForge.
13. XForms is supported experimentally in nightly builds dated after 28 January 2005 . Requires installation of an extension.
14. Opera switches to presentation mode on full screen.

2. Gecko-based browsers do not support WML natively, this issue is being discussed at bug 35995. There is an extension called wmlbrowser , which adds a partial WML support to Firefox, SeaMonkey, Mozilla Suite and Flock (without card navigation and WMLScript). In most cases this is quite enough to browse mobile Web.
3. Internet Explorer Mobile 6 supports XHTML Mobile Profile.
4. Microsoft Mobile Explorer was discontinued in 2002.^[78]

Browser	ActiveX [note 1]	NPAPI [note 1]	Java	Gears	RSS	Atom	other web feed

1. Internet Explorer (and Shells) 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.
2. Java support is for built-in support by the browser without a plugin.
3. Internet Explorer 7 and later
4. NPAPI and the Java-plugin were disabled by default in Chrome versions 42 and not supported in Chrome versions 45 and higher.
5. Except on linux
6. Internet Explorer did for a time support NPAPI plugins. Plugins that functioned in the Netscape browser also functioned in Internet Explorer. This was due to a small ActiveX control implemented within a "plugin.ocx" file that acted as a shim between the ActiveX based browser and the NPAPI plugin. The IE browser would load the control and use it to host plugins specified within the page. However, Microsoft made the claim that the NPAPI plugins (or the IE implementation of the API) were a security issue and dropped support for them in version 5.5 SP2.^[79][80][81]
7. Internet Explorer 8 supports syndicated content in hAtom / hSlice microformat by the name of a feature known as Web Slices. Internet Explorer 4.0—7 supported CDF.
8. RSS and ATOM feed autodetection in Konqueror depends on the aKregator package which is installed with kdepim.
9. Safari has Java only on OS X. Safari for Windows needs a plugin.
10. Safari has Gears only on OS X 10.4+. Windows is not supported
11. RSS and ATOM feed autodetection in Epiphany depends on the Newsfeed extension which is included with Epiphany-extensions.

1. It is possible to compile Amaya with JavaScript enabled, using the CVS version and SpiderMonkey. However, this is still experimental and only a small subset of DOM 1 is available.
2. XPath is a part of DOM 3, but is considered separately here. A large subset of DOM 3 is accessible by extensions but not by websites.
3. Internet Explorer 5 and above has its own event registration model and its own style sheets model, but these are incompatible with DOM 2.
4. Support for JavaScript has been removed in version 2.1pre29 (change log)
5. SVG / XPath / (partial) DOM 3 is only available in the WebKit nightlies so far.

1. Many browsers have FTP support as read-only and have no upload capitilies. Read-only is marked as yes. For a comparison of clients that support upload opportunities see Comparison of FTP client software.
2. Many browsers have purposely avoided support for e-mail and newsgroups (Usenet), as these are reserved for their mail-client counterparts. For a comparison of such counterparts see comparison of e-mail clients and Comparison of Usenet newsreaders.
3. Support for 256-bit ciphers (AES for example) for SSL/TLS is only available in Windows Vista and above^[90][91]

6. Respects system-wide proxy settings.
7. IRC support can be added by installing ChatZilla.
8. Microsoft has limited support to certain "non-navigable" content, such as in <img> tags and CSS rules, for security reasons, including concerns that JavaScript embedded in a data URI may not be interpretable by script filters such as those used by web-based email clients.^[83]
9. Konqueror has full Gopher support when the kgopher KIO plugin is installed.
10. Mosaic reached only HTTP 0.9 compliance, and does not support secure communications in any way.
11. For security reasons, IDN domains are displayed as punycode if they contain certain characters or if the top level domain has not been whitelisted .
12. NNTP support can be added by installing the add-on infoRSS.
13. Firefox support for the Gopher protocol was dropped in Firefox 4 (Gecko 1.9.3) per bug 388195.
14. Possible using third party extensions like FoxTorrent
15. Includes a proxy capability for gopher support.
16. Behavior towards malicious certificates can only be set up in compile time.

Browser	JPEG	JPEG 2000	JPEG XR	WebP	GIF	PNG	APNG	MNG	TIFF [note 1]	SVG [note 2]	PDF [note 3]	2D Canvas	XBM	BMP	ICO

1. Although it was one of the first suggested WWW image formats, most browsers support TIFF by using a plugin installed by the user instead of decoding it natively.
2. 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.
3. 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 OS X.
4. 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 .
5. Support for the canvas element was added to Internet Explorer 9. Earlier versions of Internet Explorer can be made to emulate canvas using the excanvas script.
6. Internet Explorer support for XBM files was removed in Version 6.
7. Firefox and SeaMonkey partially support SVG 1.1 Full. Modules that are implemented or not implemented and details of their implementation: .
8. Chromium does not support APNG. A bug report is available . There is also a plugin Animated Portable Network Graphics#Application supportavailable.
9. Konqueror supports JPEG2000 if KDE's viewer is compiled with Jasper library.
10. Inline PDF viewing in Konqueror requires KPDF which is included in kdegraphics.
11. While lacking support for inline display of graphical elements, Lynx allows defining standalone image viewer and assigning programs to MIME types. Such program is called when user activates corresponding element, effectively allowing Lynx user to add support for arbitrary non-inlined file format.
12. Safari supports JPEG2000 through QuickTime plugin, which is an optional software bundle for Safari installation on Windows, and an integrated component in OS X.
13. Safari 3 is able to render SVG documents, but not fully .
14. Support of MNG/JNG was dropped since 6 June 2003 . There are unofficial obsolete builds with MNG/JNG called Mngzilla .
15. Mozilla applications rebranded by the GNU project, such as GNU IceCat or Iceape do not support APNG.
16. In Gecko 1.9.2 (Firefox 3.6) XBM support was dropped.
17. Netscape 6.0, 6.01 and 7.0 included native support for MNG until the code was removed in 2003 due to code size and little actual usage.
18. Support for MNG/JNG has been dropped since 4 January 2014 .
19. Opera lost APNG support when switching to the Blink layout engine.
20. Opera supports SVG 1.1 Basic.
21. QupZilla supports as much SVG specification as WebKit does: .
22. 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. This feature is not included in Firefox 3.5, however it is possible with the new Cairo backend.
