Installation Notes


  1. Double-click on the K-Meleon1.5.0en-US.exe file to start the Setup process. At any time in the process that you need to stop the K-Meleon installation, click on the Cancel button.
  2. Follow the on-screen instructions in the Setup program.
    1. If you want to get a portable installation for a USB stick for instance, make sure to uncheck the option Multi-user profiles.
    2. Choose the desired installation directory. You can install K-Meleon 1.5 over a previous installation of K-Meleon. But note that you will then have to reinstall third-party extensions like Adblock Plus.
    3. When completed, you will be given the option of letting K-Meleon start automatically.
  3. If you wish to go on using your old profile that was created by a version prior to K-Meleon 1.5, please open Edit - Preferences - Macro Extension, enable macro module compat and restart K-Meleon 1.5. This way you can also let your old Groups be converted into Sessions.

  3. Click on the Add/Remove or Change/Remove button.

Internationalization/Multi-Language Support

  • K-Meleon 1.5 is fully localizable and supports multiple languages.
  • Language packages for additional installation are available in the K-Meleon Download area.
  • Resources for creation of new K-Meleon language packages can be obtained from the Localization page.


  • K-Meleon has built-in support to run ECMAScript (a.k.a. JavaScript).

Java Applets

  • You have to install the Java Runtime Environment (JRE) to run Java applets in K-Meleon. Once installed, K-Meleon automatically detects your JRE installation and no other configuration is necessary.
  • K-Meleon has been tested with JRE 1.5. You can download JRE 1.5 from the Java website. To see if JRE is properly installed, open Help - About Plugins. If you see the Java Plug-in listed, K-Meleon properly recognizes the JRE.

Known Issues/Problems


  • When viewing web page source from dynamically generated pages, the current source may not match the displayed page.
  • The URL bar content is not updated if you go back/previous just after having edited it.

Browser Display

  • Colors do not display properly when monitor resolution is set to 256 colors since Mozilla/Gecko does not provide proper support for 256 colors. See Mozilla Bug #88560.
  • A site not displaying properly is normally caused by one of two issues:
    1. The site is not compliant with current HTML standards.
    2. The display problem is due to a Mozilla/Gecko bug.

Mouse wheel scrolling/Multiple mouse buttons

  • The Mouse Gesture support offered by the new plugin is very limited. Gestures are disabled by default, you can enable them in the plugins section of the preference panel. Users in need of more advanced gestures are advised to use a third-party program, such as StrokeIt.
  • Mouse wheel scrolling does not work with all drivers. If you have problems, try updating your driver or disabling any "helper" programs that your mouse uses.
  • K-Meleon may not recognize secondary control buttons on mice with multiple buttons. If your mouse software permits programming, you may want to try binding those buttons to the respective keyboard commands that K-Meleon uses for navigation.

Third party Plugins

  • Most Mozilla-compatible plugins work with K-Meleon. If you already have Mozilla-compatible plugins installed, K-Meleon will detect and use a number of these plugins. You can download Mozilla/Netscape-compatible plugins from here.
  • The most current versions of Flash Player and Shockwave Player support K-Meleon 1.5. To check to see if these are installed properly, visit Shockwave's test site. When installing either program if you are asked for the location of the plugins directory, use the following location: \Program Files\K-Meleon\plugins


  • K-Meleon can be configured to work properly with proxies such as Junkbuster that do not support the most recent HTTP 1.1 specification. Detailed proxy settings can be made under Edit - Preferences - Proxy.
