My PC runs Windows XP Home SP2.

I am asking the following question because I am new to having more than one
browser on my PC.

Last Friday, I downloaded Firefox to my PC, as a second browser, besides
Internet Explorer.

Under my control panel, "Add or Remove Programs," it says for Flash Player,
"Adobe Flash Player 9 ActiveX."

When I check the Adobe Flash page that tells which version I have, it says
that I have Version 9.0.16.0.

Is this copy only for Internet Explorer, or do I need a separate copy as a
plug-in for Firefox, also?

Thank you.
