Open hyperlink with Firefox when IE is default browser?

How do you force a hyperlink in Excel to open with Firefox, when IE is the default browser?

I do not have access to change the default browser, as I am on a work computer.

Thank you in advance.

Still having problems with this, does anyone know how this is possible?
