launchy.xml file usage

Launchy is now (from version 2.5.0 and up) able to use a XML file to add custom applications. So you can add your own applications to Launchy's context menu. At startup Launchy will look for a file called launchy.xml in the chrome directory in your profile. Get help in finding the path of your Mozilla profile.

You can use this page to create a launchy.xml file. The content of the launchy.xml should look like this:

<?xml version="1.0" encoding="UTF-8"?>
<configurations xmlns="">
    <label>Mozilla Composer</label>
    <command>c:\program files\\nightly\mozilla\mozilla.exe</command>

label: The name of the application required
command: The full path to the executable for the application required
arguments: The arguments for the application optional
type: The type of application required. The following types are supported:

  1. Browsers (e.g. Mozilla Firefox)
  2. Mail clients (e.g. Mozilla Thunderbird)
  3. Media clients (e.g. Windows Media Player)
  4. FTP clients (e.g. WS_FTP)
  5. Download Managers (e.g. FlashGet)
  6. File Explorers (e.g. Windows Explorer)
  7. Editors (e.g. UltraEdit)
  8. View Viewers (e.g. XnView)

You can use both %ProgramFiles% and %SystemRoot% and %HOMEDRIVE% and %HOMEPATH% in the command and arguments and they are substitutes with their appropriated values.

You can also use the special %GeckoDrive% that holds the drive on which the current running Gecko application is located on.


These screenshot will provide you with a idea on what Launchy looks like. Not all supported applications are shown.

Using the Launchy toolbar button Right clicking on a mailto link Right clicking on FTP link Right clicking on a image


If you use Mozilla Firefox 0.9 or later use the Extension Manager to access the settings of Launchy.

If you use Mozilla 1.x you can access the settings of Launchy by going to Edit -> Preferences... -> Launchy


If you use Mozilla Firefox 0.9 or later use the Extension Manager to uninstall Launchy.

If you use Mozilla 1.x you can uninstall Launchy by using the Extension Uninstaller.


  • Why isn't the _______ application support? Basically because I dont use the _______ application. File a bug and specify how to detect the application in the Windows registry and I'll might add support for it.
  • If you install any of the supported applications while your browser with Launchy is running you need to restart your browser
  • Mozilla, Mozilla Firefox and Mozilla Thunderbird must to be installed using the official installers. Otherwise they can't be detected.


If you think you found a bug or have a suggestion for a enhancement please file a bug and I'll look at it.

But please see if the bug already has been filed.


These are some of the common question about Launchy:

I get a menuitem under Launchy saying Launchy is disabled! getRegistryEntry isn't available.. Why?

Please get a newer build of Mozilla Firefox.

I get a menuitem under Launchy saying Launchy is disabled! No supported applications installed.. Why?

This is because no supported applications were found. Quite amazing but true.


In the Launchy options you can enable debug mode so that debug messages will appear in the JavaScript console when running Launchy.
