Compatibility/Software for using MediaWiki

Grade A
All current major web browsers are compatible with most versions of MediaWiki. "Grade A" functionality is maintained for the following browser requirements:


 * Internet Explorer 9+
 * Firefox 4+
 * Safari 5.0+
 * Opera 11.6+
 * Chrome 17+

Grade B
Basic compatibility is maintained for legacy versions of web browsers until they fall to a sufficiently stats>stats:wikimedia/squids/SquidReportClients.htm|low level of utilization (typically under 0.1%). In particular, compatibility is currently maintained for:


 * Internet Explorer 6+
 * Firefox 2.0+
 * Safari 3.0+
 * Opera 10.0+
 * Chrome 9+

Browsers which are not explicitly marked as incompatible are often generally compatible. Support is not guaranteed for old non-standards compatible browsers and issues with those browsers might not be resolved. Security vulnerabilities affecting any browser will be addressed if possible.

Mobile browsers
In addition, MediaWiki supports reading and navigation (but not necessarily contributing) in several mobile browsers. Be aware that mobile versions of Safari, Firefox, and Opera are not quite the same as their desktop equivalents. While built on the same rendering engines, they may lack support for some features, add support for other mobile-specific features (such as touch events), or alter the display of pages to better fit on a small screen.

CSS
MediaWiki is compatible with user agents which do not process CSS3 markup. Some additional features are available to browsers which can process these styles.

JavaScript
MediaWiki is accessible to user agents which do not process JavaScript. MediaWiki degrades gracefully and all essential functionality works without JavaScript, although some things might be less convenient.

Text-only browsers
MediaWiki is accessible to text-only user agents such as Lynx, and to interpreters such as JAWS. Some functionality is reduced.

Note that older text-only browsers like Lynx are not representative of text-to-speech assistive tools like JAWS and other screen readers, which tie into browsers such as Internet Explorer and Firefox through their accessibility interfaces and make use of CSS styles, dynamic JavaScript, etc.
