The available resources are grouped into different categories depending on what you want to do.
The best source for K-Meleon information is in the Documentation section. There is also the User's Guide and Reference Manual, both for K-Meleon 0.7 and last updated in 2003. Among the external K-Meleon resources you can find some links to other general K-Meleon pages.
The skinning tutorial shows you how to install a new skin that you have downloaded from the Themes page. You can also download older skins for 1.1.x & previous versions Old Skins. Microsoft Support microsoftofficesupport.org Extra Throbbers can be downloaded and used together with any skin or theme. The external K-Meleon resources page has links to skins and themes pages located throughout the web. To customize your Windows desktop or personal web page there is also a list of Icons, Buttons, and Banners for K-Meleon. Most of the above pages are slightly outdated though.
You can download translated versions of the K-Meleon menus from our Localization resource section. That is also the place where you should find links and pointers to help you localize the Mozilla part of K-Meleon.
This information is kept in the ConfigFiles. You can edit these files through the PreferencesDialog. Beginners should use caution when editing these files and it is helpful to create a test profile for extensive customization. Strongly advised to make a safety copy of the edited files first, so you can always undo any changes.
Much of K-Meleon's behaviour can be altered through the PreferencesDialog. Even more can be altered by editing the PrefsJS?, UserJS, UserChromeCSS? or UserContentCSS files directly. These files are read by the Mozilla/Gecko rendering engine. Further information is available in the following documents.
The central and most complete place where macros, extensions etc. are first posted, where descriptions, screenshots and support may be found.
K-Meleon has a MacroLanguage that allows you to extend K-Meleon's functionality. A set of ready made macros are to be found in the meanwhile outdated Macro Library (in the last years hundreds of new macros got only posted in the forum, see above.)
K-Meleon Extensions Central: http://kmext.sourceforge.net is the place where you will find lots of categorized macro extensions written especially for K-Meleon, along with some popular mozilla xpi extensions modified to work with K-Meleon. Largely the same as in the Extensions Forum but sorted into handy categories and with much less description. This archive has also not been updated since some time. So the version informations may be outdated too, but despite it most macros still work with the newest KM-versions as well. And the rest usually just requires small modifications to keep working, except the complex xpi-addons.
(broken link) K-Meleon Extension Setup (KMES): On the K-Meleon Extension Setup pages you can find a description of this extension setup system and more interesting for the users, a lot of extensions (some Mozilla extensions, for example) adapted for K-Meleon.
You can, for instance, install and use an external bookmarks manager or an external cookies manager together with K-Meleon. Or you can use an external mouse gestures program. You can also use a download manager or miscellaneous tools like a tool to make K-Meleon your default browser or a password manager.
The skinning tutorial shows you which files to edit to make K-Meleon look the way you want. Visit the ThemeTools page to see a some of the recommended applications that can be used to help create K-Meleon themes.
K-Meleon uses Gecko, the rendering engine from Mozilla.org, and should be detected as such. You should use K-Meleon to see how Gecko handles your pages, not how K-Meleon handles your pages. Gecko aims to be fully standards compliant. If K-Meleon fails to follow the standards due to limitations in Gecko (and thus is also visible in Mozilla and/or mfcEmbed) you should report your findings to bugzilla. If K-Meleon is the only browser that fails to follow the standards on a certain page, it should be reported to our bug database. Never ever try to get K-Meleon to "work around" bugs we have. Write standards complaint pages and let us know if we fail to handle them correctly. That's all.
On the Unofficial K-Meleons page you can find unofficial versions that could be interesting for you.
Non-official plugins are available here.
