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 won't 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 can 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' live bookmarks and favicons. These will be lost when the bookmarks file is overwitten by K-Meleon's bookmarks plugin. Bear this in mind when you answer the question "The Bookmarks file was not created by this plugin. Would you like to save your changes?".

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.

Note: K-Meleon's hotlist plugin is currently not fully compatible with Opera 9.

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.
