59. ^¹The option "Do not allow any site to show pop-ups" in Google Chrome, which is the default, actually allows sites to show pop-ups which are not considered harmful.
60. ^¹²³Although text browsers don't have dialog windows, their prompts behave as modal dialogs – block the input until answer is received.
61. ^This functionality is handled by third-party software by browser's design.
62. ^¹On macOS systems, caret navigation (called "Full Keyboard Access") can be enabled systemwide.

71. ^¹²Mouse gesture support can be added by installing extensions like All-in-One Gestures (Firefox-only) and Mouse Gestures .
72. ^¹Firefox works with a number of screen readers such as JAWS (screen reader) and Microsoft Speech API through extensions.{{which |date=March 2012}}
73. ^¹Internet Explorer 8 supports caret browsing.
74. ^¹TTS 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.
75. ^¹Internet 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.

97. ^¹²³⁴⁵⁶Depends on the layout engine which is chosen: Trident or Gecko or WebKit.
98. ^¹²³⁴⁵⁶⁷⁸⁹¹⁰Depends on the layout engine which is chosen: Trident or Gecko.
99. ^¹²CSS 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).
100. ^¹²Frames and frame sets are obsolete and non-conforming in HTML5. They should not be used by authors.
101. ^¹²LINK as a navigational aid, as distinct from non-navigational uses of LINK.
102. ^¹²³⁴Not in standard install, but provided by extension.
103. ^¹²³⁴XHTML 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).
104. ^¹Dillo displays frames as links that the user can click on.
105. ^¹²³Available with the MathPlayer plugin.
106. ^¹Available with the FormsPlayer plugin and several other plugins.
107. ^¹XForms is supported experimentally in nightly builds dated after 28 January 2005 [https://developer.mozilla.org/en-US/docs/Archive/Web/XForms]. Requires installation of an extension.
108. ^¹²Web Forms 2.0 can be emulated in IE using DHTML behaviours, [https://sourceforge.net/projects/wf2/ available from SourceForge].

113. ^¹²³⁴Internet 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.
114. ^¹Java support is for built-in support by the browser without a plugin.
115. ^¹²NPAPI and the Java-plugin were disabled by default in Chrome versions 42 and not supported in Chrome versions 45 and higher.
116. ^¹²³⁴⁵⁶⁷⁸Internet Explorer 7 and later
117. ^¹²RSS and ATOM feed autodetection in Konqueror depends on the aKregator package which is installed with kdepim.
118. ^¹²RSS and ATOM feed autodetection in Epiphany depends on the Newsfeed extension which is included with Epiphany-extensions.
119. ^¹Safari has Gears only on Mac OS X 10.4+. Windows is not supported
120. ^¹Safari has Java only on macOS. Safari for Windows needs a plugin.
121. ^¹Internet 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.
122. ^¹Only supported in Trident mode.
123. ^¹Only supported in Blink mode.
124. ^¹²Internet Explorer 5 and above has its own event registration model and its own style sheets model, but these are incompatible with DOM 2.
125. ^¹²³⁴⁵⁶⁷⁸⁹¹⁰¹¹¹²XPath 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.
126. ^¹²³⁴⁵SVG / XPath / (partial) DOM 3 is only available in the WebKit nightlies so far.
127. ^¹²³It is possible to compile [https://web.archive.org/web/20071225120656/http://www.maths-informatique-jeux.com/international/javascript_in_amaya/ 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.
128. ^¹Support for JavaScript has been removed in version 2.1pre29 (change log)

139. ^¹²Many 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.
140. ^¹²Many 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.

159. ^¹²While 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.
160. ^¹Konqueror supports JPEG2000 if KDE's viewer is compiled with Jasper library.
161. ^¹²³⁴Internet Explorer support for XBM files was removed in Version 6.
162. ^¹²Internet Explorer supports PNG images but is unable to correctly display images with gamma correction or color correction.{{Citation needed|date=January 2011}} Versions of Internet Explorer prior to version 7 are unable to correctly display images with alpha channel (for transparency) without additional coding .
163. ^¹Support of MNG/JNG was dropped since 6 June 2003 [https://www-archive.mozilla.org/status/2003-06-06.html] . There are unofficial obsolete builds with MNG/JNG called Mngzilla .
164. ^¹Support for MNG/JNG has been dropped since 4 January 2014 [https://www.collabora.com/about-us/blog/2014/01/06/netsurf-developer-workshop-redux/] .
165. ^¹²Although 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.
166. ^¹²SVG 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.
167. ^¹²³⁴Firefox and SeaMonkey partially support SVG 1.1 Full. Modules that are implemented or not implemented and details of their implementation: [https://developer.mozilla.org/en-US/docs/SVG_in_Firefox].
168. ^¹Opera supports SVG 1.1 Basic.
169. ^¹²Safari supports JPEG2000 through QuickTime plugin, which is an optional software bundle for Safari installation on Windows, and an integrated component in macOS.
170. ^¹²Safari 3 is able to render SVG documents, but not fully .
171. ^¹²Most 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 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 macOS.
172. ^¹Inline PDF viewing in Konqueror requires KPDF which is included in kdegraphics.
173. ^¹²Support for the canvas element was added to Internet Explorer 9. Earlier versions of Internet Explorer can be made to emulate canvas using the [https://code.google.com/p/explorercanvas/ excanvas] script.
174. ^¹²With 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.
175. ^¹Netscape 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.
176. ^¹In Gecko 1.9.2 (Firefox 3.6) XBM support was dropped.
177. ^¹²Mozilla applications rebranded by the GNU project, such as GNU IceCat or Iceape do not support APNG.{{citation needed|date=August 2015}}
178. ^¹²³For Chromium prior to version 59 there is support via an extension.
179. ^¹Falkon supports as much SVG specification as WebKit does: .
180. ^¹Opera is currently supporting APNG on their Beta and Dev builds.

Operating system support

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 macOS 10 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 some smart TVs).

Both the web browser and OS means most recent version, example: Windows 8 with Internet Explorer 10.

Browser features

Information about what common browser features are implemented natively (without third-party add-ons).

Accessibility features

Information about what common accessibility features are implemented natively (without third-party add-ons). Browsers that do not support pop-ups have no need for pop-up blocking abilities, so that field is marked as N/A.

Accessibility features (continued)

Information about what common accessibility features are implemented natively (without third-party add-ons).

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).

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.^[90]

As new tests are added, bogus ones removed, etc., new versions of [https://html5test.com/ html5test.com] become available as preliminary [https://beta.html5test.com/ beta] or even [https://alpha.html5test.com/ 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.

Web technology support

Information about what web standards, and technologies the browsers support, except for JavaScript. External links lead to information about support in future versions of the browsers or extensions that provide such functionality.

Plugins and syndicated content support

Information about what web standards, and technologies the browsers support. External links lead to information about support in future versions of the browsers or extensions that provide such functionality.

JavaScript support

Information about what JavaScript technologies the browsers support. Note that although XPath is used by XSLT, it is only considered here if it can be accessed using JavaScript. External links lead to information about support in future versions of the browsers or extensions that provide such functionality, e.g., Babel.

Protocol support

Information about what internet protocols the browsers support (in addition to HTTP that all (modern) browser should and do fully support^[325]). External links lead to information about support in future versions of the browsers or extensions that provide such functionality.

Image format support

Information about what image formats the browsers support. External links lead to information about support in future versions of the browsers or extensions that provide such functionality.

Native multimedia support
