Thanks for the reply
Sorry as I said I'm fairly new Why would it only work in IE? Bad part is that this is a part of a firefox extension

. That could be my whole issue.
The space for the ping I thought would be in place due to the double quotes. Either way I cannot even get the prompt to open for the ping to be placed.
I am calling the function with a button in XUL as outlined below
<toolbarbutton id="customer_direct_helper-toolbar-pinger"
tooltiptext="&customer_direct_helperToolbarpinger.tooltip;"
label="&customer_direct_helperToolbarpinger.label;" oncommand="customer_direct_helper.onToolbarpingerCommand()" />
