Hi,

Most likely it isn't possible in the normal way, because Firefox doesn't allow direct execution from its interface. You can try this as a bookmark: file:///DriveLetter:/folder/subfolder/app.exe

You can look at the PrefBar extension.

• PrefBar: https://addons.mozilla.org/firefox/addon/prefbar/

That extension includes support for this with a few demo buttons to check it out.

prefbarExecute("C:\\Windows\\notepad.exe");

Thanks for the prompt reply. I will look at that. Regards. Mike
