MSExplorer 6 does not work well with abcestry.com, so I want to use the recommended Firefox3 only when I want to access ancestry.com. I have not installed Firefox3 yet because i am concerned it will over ride my Explorer6.

You can download and install Firefox from here. Since you want IE to be your primary browser, make sure that when Firefox asks you if it should be the "default" browser, you click No.
