Gecko is a free HTML rendering engine that is mainly used in a number of web browsers to display web pages . The software reads HTML files, style sheets and other resources (such as media data ) and displays the interpreted result on the screen as formatted output.
Gecko is mainly used in Mozilla products such as Firefox , SeaMonkey or Thunderbird . As of version 5, the current version number is identical to the current Firefox main version number.
technology
In the development of Gecko, special attention is paid to the full support of open Internet standards such as XHTML , the older HTML , CSS , the Document Object Model of the W3C , XML , RDF and JavaScript .
The Gecko engine was written in the C ++ programming language. It is free software and can therefore be used by anyone free of charge and adapted under the conditions of the MPL to meet their own requirements. Gecko's previous names were Raptor and NGLayout . NGLayout actually meant "Next Generation Layout", but it was later often referred to as "Netscape Gecko Layout".
The engine also includes an editor component that supports plain text and HTML.
Applications can use the module with the Gecko library libxul, via XULRunner (which itself uses libxul) or via Gecko software with its own integrated runtime environment such as Mozilla Firefox up to version 2.

| 1.8 | November 29, 2005 | Firefox 1.5 | Support for SVG and Canvas , improvements in JavaScript 1.5 and CSS 2/3. |
| 1.8.1 | October 24, 2006 | Firefox 2.0 | |
| 1.9 | June 17, 2008 | Firefox 3.0 | One of the main goals of Gecko 1.9 was the major overhaul of the graphical output. Instead of the platform API, the cross-platform graphics library Cairo is used. This allows the screen output to be accelerated with 3D graphics hardware. It is also possible to save the output in formats such as PNG or PDF . So the user can export web pages in these formats.
In addition, the code in the reflow refactor branch has been heavily revised, e.g. B. Enable CSS declarations like display: inline-block. This means that the Acid2 test is also passed. |

use
The browsers Netscape Navigator , Mozilla , SeaMonkey and Mozilla Firefox use the Gecko rendering engine to display content. But the graphical user interface is also rendered by the Gecko Engine in these browsers. For this purpose, Mozilla developed XUL as a description language for GUIs, which is interpreted by Gecko. XUL applications can use XULRunner as a runtime environment for this . There are also applications like Mozilla Sunbird that don't use (X) HTML rendering. For the platform macOS Gecko was in Mozilla Camino , for Linux z. B. integrated in Galeon (for Gnome desktop with GTK + -2 library), Epiphany (until 2009) and Skipstone. In July 2011 it was also announced that Mozilla was developing a mobile phone operating system based on the Gecko engine. Since Mozilla removed the option to embed the Gecko Layout Engine in other programs in 2011, Gecko is now only used in Mozilla products. Other projects that previously used Gecko have either switched to WebKit or have been discontinued.
Programs that Gecko use to render HTML and XML content include:
