How to add parameter to run command keyboard shortcut

Thanks to the SevenForums tutorial at:

Run Command - Create Shortcut

I know how to create a desktop shortcut for the run command, and can pin it to the taskbar.

I thought I could add a parameter by clicking on the end of the Target line in the shortcut's properties:

%windir%\explorer.exe shell:::{2559a1f3-21d7-11d4-bdaf-00c04f60b9f0}

and typing in the parameter I want (in this case, firefox.exe, with a switch to load a profile from a specific folder.)

Unfortunately, that's not working as I had hoped. With or without the parameter, I still get the Run command prompt window telling me to:

Type the name of a program, folder, document or Internet resource, and Windows will open it for you.

I'd like to bypass this window, and have the shortcut load Firefox with the specified profile.

Can anyone tell me how to do this?

Thanks for the response, Brink. I was able to make a shortcut to firefox.exe, but not with the parameter I need. Even adding the -p switch after firefox.exe gives me a 'name specified in the Target box is not valid' error.

If there's a way to include a parameter in a shortcut, I'm very interested! Otherwise, I'm still stuck.

That put me on the right track, Ztruker; thank you. I couldn't get it to work with just the -p switch -- which kept pulling up the profile manager -- but when I edited the shortcut target line to read:

"c:\Program Files(x86)\Mozilla Firefox\firefox.exe" -profile "x:\users\myname\AppData\Roaming\Mozilla\Firefox\Profiles\myname.default"

it consistently worked.

(For the benefit of anyone wandering across this thread with a similar problem: please note quotes around "c:\Program Files(x86)\Mozilla Firefox\firefox.exe" and "x:\users\myname\AppData\Roaming\Mozilla\Firefox\Profiles\myname.default" but not around -profile between the two.)
