K-Meleon is a free and open-source, lightweight web browser for Microsoft Windows. It uses the native Windows API to create its user interface. Early versions of K-Meleon rendered web pages with Gecko, Mozilla's browser layout engine, which Mozilla's browser Firefox and its email client Thunderbird also use. K-Meleon became a popular Windows browser and was available as an optional default browser in Europe via BrowserChoice.eu. K-Meleon continued to use Gecko for several years after Mozilla deprecated embedding it. Current versions of K-Meleon use the Goanna layout engine, a fork of Gecko created for the browser Pale Moon.

K-Meleon began with the goal of being faster and lighter than Mozilla's original Internet suite. Until 2011, K-Meleon embedded Gecko in a stripped-down interface. Throughout its lifespan, K-Meleon has required small amounts of random-access memory (RAM). K-Meleon 76 supports discontinued versions of Windows such as Windows XP and Windows Vista. Mozilla no longer supports these platforms after their Firefox Quantum rewrite.

Customization is another primary design goal. Users can change the toolbars, menus, and keyboard shortcuts from text-based configuration files. K-Meleon supports macros, which are small browser extensions that users can examine, write, or edit in a text editor. K-Meleon's custom configuration files can trigger macros. Reviews describe the customization features as versatile but intimidating to the average user. Due to its adaptability, K-Meleon was recommended for Internet cafés and libraries in the early 2000s.

History

Christophe Thibault started the K-Meleon project in the 2000s,{{cite news |url=http://www.betanews.com/article/KMeleon_Browser_Showcases_Gecko/966933295 |title=K-Meleon Browser Showcases Gecko |work=BetaNews |publisher=BetaNews, Inc. |date=22 August 2000 |access-date=8 November 2011 |last=Mook |first=Nate |archive-date=9 February 2009 |archive-url=https://web.archive.org/web/20090209060714/http://www.betanews.com/article/KMeleon_Browser_Showcases_Gecko/966933295 |url-status=live}} when many new browsers were launched.{{cite magazine |last=McCracken |first=Harry |title=For Browsers, the Best of Times is Now |magazine=PC World |publisher=International Data Group |pages=15 |date=March 2007}} To open-source their once-dominant Netscape Communicator Internet suite, Netscape founded the Mozilla project.{{cite news |title=Rebel Web browsers worth considering |last=Dunsdon |first=Nicole |date=11 October 2000 |page=TB4 |newspaper=Calgary Herald}} K-Meleon was one of several browsers to use Mozilla's browser engine Gecko.{{cite book |title=Creating Applications with Mozilla |chapter-url=https://www.oreilly.com/library/view/creating-applications-with/9780596000523/05_chapter-01.html |access-date=2 February 2023 |chapter=Mozilla as Platform |publisher=O'Reilly Media |date=24 September 2002 |editor=Boswell, David |last1=Boswell |first1=David |last2=King |first2=Brian |last3=Oeschger |first3=Ian |last4=Collins |first4=Pete |last5=Murhpy |first5=Eric |page=7 |archive-date=February 2, 2023 |archive-url=https://web.archive.org/web/20230202062215/https://www.oreilly.com/library/view/creating-applications-with/9780596000523/05_chapter-01.html |url-status=live}} Thibault designed K-Meleon to combine Gecko with native Windows interface elements, an approach that was less resource-intensive and allowed the browser to blend into its environment.{{cite web |first=Elena |last=Blanco |url=http://www.oss-watch.ac.uk/resources/webbrowser.xml#body.1_div.5 |title=Open source and the web browser |work=OSS Watch |publisher=University of Oxford |access-date=8 November 2011 |date=1 March 2005 |archive-date=29 May 2010 |archive-url=https://web.archive.org/web/20100529224825/http://www.oss-watch.ac.uk/resources/webbrowser.xml#body.1_div.5 |url-status=live}}

In 2011, Mozilla ended support for embedding the Gecko layout engine; because K-Meleon had previously relied on this API, the browser's future became uncertain.{{cite news |url=http://www.h-online.com/open/news/item/Mozilla-kills-embedding-support-for-Gecko-layout-engine-Update-1218990.html |title=Mozilla kills embedding support for Gecko layout engine |work=The H Open: News and Features |access-date=10 September 2016 |date=31 March 2011 |publisher=Heise Media |last=Walker-Morgan |first=DJ |archive-date=13 November 2012 |archive-url=https://web.archive.org/web/20121113144301/http://www.h-online.com/open/news/item/Mozilla-kills-embedding-support-for-Gecko-layout-engine-Update-1218990.html |url-status=live}}{{efn|The situation also left the future of other embedded Gecko browsers unclear.

Customization

Customization of K-Meleon's interface is possible using text-format configuration files called configs. The menus, keyboard shortcuts, and more can all be customized via K-Meleon's configuration files.{{cite news |url=https://www.pocket-lint.com/apps/news/microsoft/102551-eu-browser-ballots-boutique-options |title=Wild Wild Web – the browser ballot's lesser-known options |last=Geere |first=Duncan |date=1 March 2010 |publisher=Pocket-lint |access-date=10 September 2022 |archive-date=10 September 2022 |archive-url=https://web.archive.org/web/20220910203005/https://www.pocket-lint.com/apps/news/microsoft/102551-eu-browser-ballots-boutique-options |url-status=live}}{{cite book |title=K-Meleon 1.x Reference |chapter-url=http://freenet-homepage.de/CoolMcKluus/software/kmeleon/project/reference/cfgfiles/index.html |access-date=9 February 2023 |date=27 November 2006 |archive-url=https://web.archive.org/web/20090923123801/http://freenet-homepage.de/CoolMcKluus/software/kmeleon/project/reference/cfgfiles/index.html |archive-date=23 September 2009 |last=Kohler |first=Klaus |chapter=Configuration Files}} These configs can call upon macros, a type of extension that can be opened in a text editor.

A simple "Hello, World!" program could be written in K-Meleon's macro language that would pop up a small window with the message "Hello world!".{{cite book |title=K-Meleon User's Guide and Reference Manual |last1=Erikson |first1=Ulf |last2=Holman |last3=Mutch |last4=Moses |last5=Sachner |last6=Zarneth |publisher=K-Meleon Documentation Project |access-date=22 December 2022 |archive-date=9 February 2023 |archive-url=https://web.archive.org/web/20230209102506/https://kmeleon.sourceforge.net/manual/macro-lang.html |url-status=live |date=2002 |chapter=§ 7.7 Macro Language |chapter-url=https://kmeleon.sourceforge.net/manual/macro-lang.html}}

HelloWorld{

alert("Hello world!");

}

To trigger the macro, a keyboard accelerator could be created by adding the code below to the accelerator config, causing the macro to launch if the Ctrl, Alt, and H keys are pressed at the same time.{{cite document |last=Doozan |first=Jeff |date=2001 |title=Macro Definition File for K-Meleon 0.6 (macros.cfg) |publisher=K-Meleon |type=Documentation}} Doozan described the accelerator syntax to add a macro command as "Sample Usage: in accel.cfg KEY = macros(example)" with "example" being the name of an individual macro sections enclosed in brackets.

CTRL ALT H = macros(HelloWorld)

Custom toolbars offer more options, but the syntax is similar. The example below would create a new toolbar with a button to trigger a macro.{{cite document |last=Doozan |first=Jeff |date=2001 |title=Toolbar Definition File for K-Meleon 0.6 (toolbars.cfg) |publisher=K-Meleon |type=Documentation}} Doozan documents the formatting as "ToolBar Name { Button Name { command id (required) } }" with many optional parameters including size, "Tool Bar(16,16){ = NAME OF TOOLBAR* (WIDTH, HEIGHT), DEFAULT=(16,16)", and bitmap "image file[s]" for various states.

NewToolbar{

!NewButton{

macros(HelloWorld)

}
