Gecko	19.0	20.0	All Mozilla software, including Firefox; SeaMonkey and Galeon; Camino; K-Meleon; Flock (up to 2.x); Debian IceWeasel; GNU IceCat (formerly GNU IceWeasel); Icedove, Iceape and Iceowl; Fennec. Also used by the Maple platform in 2010 and 2011 Samsung "SmartTV" devices which are based on the build used in Firefox 3.0.
KHTML		N/A	Konqueror^†
Presto	2.10.229	2.10.238	Opera; Opera Mobile, Nintendo DS & DSi Browser; Internet Channel

Used by the LG Smart TV platform to enable web content on TVs.

^† In Konqueror, the user can switch layout engine.

Values

Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.

Value	Meaning
Yes	Indicates that the layout engine fully supports this property/element when valid values are used.
No	Indicates that the property/element is completely ignored.
Partial	Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
Incorrect	Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
Experimental	Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
Dropped	Indicates that the property/element is no longer supported.
Nightly build	Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
Depends	Indicates that the property/element is supported only on certain platforms, or if certain settings are configured.

Notes

^ Gecko uses the libpr0n library to render images.
^ Does not have any native image support. This is by design: in Konqueror, multimedia files are handled by KParts.
^ JPEG 2000 support is only available on the Mac OS X platform.^{[w 1]} (Note that the referenced link leads to the Mozilla Bugzilla, where this was brought up and confirmed.)
^ Prince uses the libtiff library to load TIFF images.
^ Trident dropped support for XBM in Internet Explorer version 6.0.
^ As of 5.2.3, the last publicly released version.
^ Gecko dropped XBM support in version 1.9.2.^{[g 6]}
^ Prince uses the libjpeg library from the Independent JPEG Group to load JPEG images.
^ Trident only displays progressive JPEGs once they have been completely downloaded.
^ Prince uses the libungif library to load GIF images.
^ Prince uses the libpng library to load PNG images.
^ There are 15 combinations of the color modes in PNG but not all modes are available in every image editor.
^ ^a ^b Gecko and Presto currently support gamma correction for all color profiles except for ICC-profile.^[4]
^ Webkit incorrectly applies gamma correction to unlabeled PNGs.^{[w 5]}
^ In Trident, interlaced PNGs are displayed progressively, but in 1D instead of 2D.
