The fact that you
a) don't know how to do this, and
b) don't have a choice over which browser to use
leads me to conclude that
a) your company has an IT department, and
b) you're not in it.
I suggest you get in touch with them, as although the task you wish is simple, they're not going to be happy being stuck supporting some code they didn't write, that one of their users "got off the internet somewhere."
