Extensions

Extensions can add new capabilities to K-Meleon. There are several types of extensions for K-Meleon that each gives deep access to the browser:

• Extensions can use Mozilla's XUL/XPCOM platform previously used in Firefox.
• Extensions can also be written as packages specifically for K-Meleon.
• Finally, K-Meleon can run small macros written in K-Meleon's Macro Language.

Current Firefox extensions are not compatible with K-Meleon. Mozilla no longer supports XUL-based add-ons. They now use the more limited WebExtensions API for current Firefox extensions. Legacy Firefox extensions (and some extensions for Pale Moon) can run in K-Meleon, but often need to be modified or updated.

K-Meleon-specific extensions can be installed with the K-Meleon Extensions Manager or by manually extracting the files. The most common type of extension for K-Meleon is the macro. Macros are small extensions. They come in simple text files that can be opened and read by any user.

Extensions are separate from third-party plugins and native Kplugins. K-Meleon can use third-party plugins to handle content that the browser can't natively render. Kplugins are written specifically for K-Meleon, and native Kplugins power many of K-Meleon's features.

Third-party authors provide extensions for K-Meleon. Be aware that poorly written extensions can cause stability and security issues. Use at your own risk.

K-Meleon Extensions Central

Visit http://kmext.sourceforge.net for K-Meleon extensions. The site includes extensions modified to work with K-Meleon and extensions written for K-Meleon.

To install a K-Meleon extension:

1. Download the K-Meleon Extensions Manager for your operating system.
2. Extract the extension manager packages directly into your K-Meleon folder.
3. Go to Tools - Extension Manager.
4. Click the Run Installer button. A file dialog will open. Browse to an extension saved in the .7z format.

With the Extensions Manager, you can also install extensions directly from a webpage. For direct installation, right-click the link to an extension and choose KM Extension. K-Meleon will then restart with the extension installed.

Extensions Forum and Macros

The main place to find new extensions is on the K-Meleon extensions forum: http://kmeleonbrowser.org/forum/list.php?9

Many extensions are distributed as macros and can be installed by saving them to the K-Meleon > macros folder. You can open your macros folder by going to Configuration > Macros in the main menu.

Some extensions are packaged for the K-Meleon Extensions Manager, but many extensions on the forum have to be manually installed. To manually install an extension package:

1. Download the compressed file.
2. Copy and Paste the root K-Meleon folder to create a backup.
3. Extract the extension directly into your root K-Meleon folder.
4. Restart and test K-Meleon.

XUL-based extensions

K-Meleon can run XUL-based add-ons written for K-Meleon. It can also run some add-ons written for Pale Moon, Thunderbird, legacy Firefox, or Sea Monkey although features may require modification to work. XUL-based extensions are distributed as .xpi files. You can install these with any of the following methods:

• Click a link to an .xpi file on any web page for automatic installation.
• Install a downloaded .xpi by going to File > Open CTR+O >> All Files and choosing your extension.
• Choose Install From File on the add-ons preferences page.

You can view your current XUL-based extensions and manage them from the add-ons page. To go there now:

1. Type about:addons into the address bar.
2. Press enter.
3. Click on the Extensions tab.
4. Click the more link beside an extension, or click the gear icon to install extensions.

If you would like to create a XUL-based extension for K-Meleon, you can use K-Meleon's JsbridgePlugin to build K-Meleon menus and run macros from within a XUL-based extension. There are several extensions in the forum specifically written for K-Meleon to learn from:

• Kris88's screenshot extension: http://kmeleonbrowser.org/forum/read.php?9,153889,page=1
• Adodupan's restart extensions: http://kmeleonbrowser.org/forum/read.php?1,143142,143159
