Features


Does K-Meleon support current web standards?

Yes. K-Meleon uses the Gecko rendering engine developed by Mozilla, which is also used by Firefox. Gecko provides excellent support for current (X)HTML, CSS and DOM standards. K-Meleon has built-in support to run JavaScript.


Does K-Meleon support secure (encrypted) transmissions?

Yes. K-Meleon 1.1 provides SSL (version 3) and TLS support.


Does K-Meleon support tabbed browsing?

Yes, through the Layered Windows Plugin. Which is why the 'tabs' in K-Meleon are called 'layers' (there's a technical difference between layers and tabs that has to do with to the window management).


Does K-Meleon support Java?

Yes. To run Java applets in K-Meleon, you have to install the Java Runtime Environment (JRE). Once installed, K-Meleon automatically detects your JRE installation and no other configuration is necessary. You can download the JRE from the Java website. To see if the JRE is properly installed, open Help > About Plugins. If you see the Java Plug-in listed, K-Meleon properly recognizes the JRE.
Note: Java may not work when you change K-Meleon's browser identification (UserAgent) string.


What is the K-Meleon Loader?

The K-Meleon Loader preloads portions of the K-Meleon browser and thus allows it to launch more quickly - especially on low-end hardware. Be aware that the K-Meleon browser keeps running as long as the K-Meleon Loader is running. Some changes to the configuration of K-Meleon will not take effect until you close and restart the browser. When using it, you also have to close and restart the Loader to make such changes take effect. Review the details here.


What privacy features does K-Meleon include?

Under Tools > Privacy you can quickly enable/disable privacy-related features such as cookies, Java, JavaScript and popup windows, frames and HTTP referers. The Privacy Bar provides even more direct access. Cookie acceptance, image loading and popup blocking can be configured in detail through Edit > Preferences. Some more privacy-related settings can be found in Edit > Advanced Preferences. K-Meleon's UserAgent string can be quickly changed through Tools > User Agent. The Privacy Plugin empowers you to delete privacy-related data such as cache, cookies, history and passwords automatically at startup or at shutdown, or manually at any time. See Configurable Security Policies for more details on advanced privacy features.


Why does K-Meleon not include feature "X" (e-mail client, etc.)?

K-Meleon is intended to be a fast, customizable, lightweight web browser. It is designed to be a browser only, not a suite. Thus, it does not include features such as an e-mail client or a web page editor, which could bloat and slow K-Meleon down. Users are encouraged to use their favorite applications for these and other particular purposes. The K-Meleon developers will consider enhancements that improve the performance and usefulness of the browser.

Bookmarking Systems


How do I use my existing Netscape/Mozilla Bookmarks?

The first time K-Meleon is run with the Netscape Bookmark Plugin enabled, it automatically creates a new bookmarks file in your profile directory. You also have the possibility of using your existing Netscape, Mozilla or Firefox bookmarks file in K-Meleon. Open Edit > Preferences and go to the Plugins section. Select Netscape Bookmark Plugin and press Configure.... This will open the Netscape Bookmarks Settings dialog where you can set the location of your bookmarks file. Specify the location of your existing Netscape, Mozilla/SeaMonkey or Firefox bookmarks file here.

Mozilla/SeaMonkey, Netscape and Firefox store their bookmarks file in their profile directory. Its location depends on your operating system. The following example is for the Mozilla/SeaMonkey profile directory:

Windows 95
C:\Windows\Mozilla\<profile name>\<random>.slt
Windows 98/ME
C:\Windows\Application Data\Mozilla\<profile name>\<random>.slt
Windows NT
C:\WinNT\Profiles\<user name>\Application Data\Mozilla\Profiles\<profile name>\<random>.slt
Windows 2000/XP
C:\Documents and Settings\<user name>\Application Data\Mozilla\Profiles\<profile name>\<random>.slt

Netscape creates its own folder in the same folder that contains the Mozilla folder. Firefox creates its folder within the Mozilla folder.

Note: K-Meleon's bookmarks plugin does currently not support Firefox's live bookmarks and favicons.


How do I use my existing Internet Explorer Favorites?

K-Meleon's IE Favorites Plugin automatically locates and uses your Favorites. This plugin does not import your Favorites, it allows you to share your Favorites between K-Meleon and Internet Explorer!

K-Meleon's Netscape Bookmark Plugin allows you to import your Favorites into your bookmarks file. Choose Bookmarks > Edit... and then press Import Favorites.


How do I use my existing Opera Hotlist?

The first time K-Meleon is run with the Opera Hotlist Plugin enabled, it will automatically create a new empty hotlist file in your profile directory. You also have the possibility of using your existing Opera hotlist file in K-Meleon. Open Edit > Preferences and go to the Plugins section. Select Opera Hotlist Plugin and press Configure.... This will open the Opera Hotlist Settings dialog where you can set the location of your hotlist file. Specify the location of your existing Opera hotlist file here.


What are Hotlinks?

Hotlinks are provided through the Macro Extension Plugin and are in a way K-Meleon's own bookmarking system. Very simple, yet efficient. Through Tools > Hotlinks... you have the possibility to assign an URL to each of the key combinations Ctrl+0, Ctrl+1, ..., Ctrl+9. Note that javascript: URLs usually won't have the desired effect when set to open in a new window/layer.

Troubleshooting


Why does website "X" not display/work properly? Is it a K-Meleon bug?

Probably not. A site not displaying/working properly is normally caused by one of three issues:

  1. The site is not compliant with current HTML standards.
    Try out how the site is looking in Internet Explorer (e.g. press Ctrl+Alt+I). Still a lot of websites use proprietary HTML markup and/or JavaScript code that only works correct in IE.
  2. The site is using browser-specific JavaScript.
    Try out how the site is working when you change K-Meleon's UserAgent string e.g. to Firefox' or SeaMonkey's. Still a lot of websites fail to detect K-Meleon as a Gecko-based browser.
  3. The display problem is due to a Mozilla bug.
    Try out how the site is looking in another Gecko-based browser e.g. Firefox or SeaMonkey.

You can report such problems to the K-Meleon Forum - somebody may attempt to determine the source of the problem. Keep in mind that the particular authors are responsible for a website, not the K-Meleon developers.


Why does my personal firewall issue an alert that K-Meleon is requesting server rights?

The Personal Security Manager (PSM) in Mozilla, which K-Meleon is built on, uses sockets for communication between its security components. These communications are internal to the browser and do not go out to the Internet. There is no danger in allowing K-Meleon this access. All Mozilla browsers behave like that.


Why does K-Meleon not display colors properly when the monitor resolution is set to 256 colors?

Mozilla/Gecko does not provide proper support for 256 colors. See Mozilla Bug #88560.


Why does the ZIP/7Z version of K-Meleon refuse to run on my system?

Your system is missing the libraries msvcp71.dll and msvcr71.dll (these are not included in the ZIP/7Z versions). You can get these files from the dll-files.com website, or dlldump.


Why is K-Meleon opening two windows or displaying a "Can't open..." error message when I open an URL from an e-mail program or an Internet Shortcut?

This type of problem is usually the result of the DDE (Dynamic Data Exchange) option being enabled in the Windows Registry for the type of URL that you are trying to open. In Windows Explorer, open Tools > Folder Options... and select the File Types tab. When you've found the type of URL in question (e.g. URL:HTTP ...), select it and click Edit.... In the list of Actions select open and click Edit.... Uncheck the Use DDE checkbox and press OK until you are finally out of the Folder Options dialog.


Why do I get an error message on Windows 9X/NT related to mfc42.dll?

Your system is missing certain libraries. See the system requirements.


Why do the Bookmarks menu and/or other plugin menus not appear?

Your system is missing certain libraries. See the system requirements.


Why aren't links opening up in K-Meleon, it's set as my default browser?

K-Meleon's Setup Assistant doesn't set HTTP and HTTPS file types to open with K-Meleon. To fix this open up Windows Explorer and click the Tools button on the menu bar, then select Folder Options... In the Folder Options window select the File Type tab. Scroll down until you see "URL:HTTP (HyperText Transfer Protocol)" under the File Types column, it's extention is (NONE). Click the advanced button, then in the Actions: list box select open, then click the Edit button. In the new window click the Browse... button then navigate to the K-Meleon.exe in it's installed directory then click ok. The default location is "C:\Program Files\K-Meleon\K-Meleon.exe" (you can just copy this WITH QUOTES if you installed it in the default directory). Add "%1" to the The Application to preform action text box. Uncheck DDE and both Ok buttons. Do the same for the URL:HTTPS file type and then you're done.
