Many useful features are hidden in K-Meleon's "about" pages. The about protocol is similar to other Mozilla-derived browsers like Firefox, SeaMonkey, or Pale Moon. To access these features:

1. Copy one of the URLs listed below like about:config.
2. Paste it into K-Meleon's address bar.
3. Press enter.

Commonly Used About Pages

about:config	Manually modify user preferences. There is a search box on the top line of the page but you can also filter preferences via the address bar. For example, if you wanted to show only toolband preferences that position the toolbars in K-Meleon you could enter about:config?filter=toolband into the address bar.
about:addons	Manage XUL-based extensions and third-party plugins. Neither kplugins nor macros will appear here. Some extensions like GreaseMonkey may add tabs to this page.
about:downloads	View and manage current or recent download activity.
about:home	Open the browser's default home page. Changing the home page for a profile will not change the browser's default.
about:	List version, copyright licenses, useragent, and attributions for K-Meleon. Browser menu: Help > About K-Meleon
about:plugins	List currently installed third-party plug-ins recognized by K-Meleon. Browser menu: Help > About Plugins

Technical About Pages

about:blank	Display a blank page. This is sometimes used for new windows or even as a homepage to open windows more quickly.
about:cache	Display browser cache information.
about:mozilla	Display Mozilla-related text.
about:about	List all about pages.
about:credits	Display a list of people who have "made a significant investment of time, with useful results, into Mozilla project-governed activities" (historically), and people who have significantly contributed to the Pale Moon project.

Adding menu options

If you frequently use one of the hidden about pages it may be helpful to add a menu option. The simplest way is to create a bookmark for the page.

You can also create menu entries for the about pages with macros. Siria's About:About macro from the forums will add a menu with many of the about pages. If you only need a menu entry for a single page, it's even simpler. Compare the two examples below to see how.

To create menu entries for about:downloads or about:addons simply:

1. Open any text editor, like Notepad or Notepad2.
2. Copy and paste the macro code below.
3. Save it as a K-Meleon macro module (.kmm) file. It can have any name but must end with .kmm, so about_pages.kmm would work but not about_pages.kmm.txt.
4. Be sure to place the macro module in the K-Meleon/macros/ folder or the Profiles/your.profile/macros/ folder.
5. Restart K-Meleon.
