Firefox is a free browser, and there's no activation required. All you have to do is download and install, then you are ready to use. If you are asked to activate, then it's a spam/virus, you should scan your PC with anti-virus/spyware programs and get rid of them.

If you need further help, please post more details, e.g. where did you download Firefox and send us a screen shot of the window that asked you to activate Firefox.
