I can't download a theme for Firefox. The Download button is gray and when I click it a drop down menu appears:"To install this add-on and thousands more, get Firefox, a free and open web browser from Mozilla. Learn more about Firefox or download anyway." Even though I have Firefox.

Your UserAgent string in Firefox is messed up by another program that you installed, and the addons website doesn't know which version of Firefox you are using. http://en.wikipedia.org/wiki/User_Agent

type about:config in the URL bar and hit Enter If you see the warning, you can confirm that you want to access that page. Filter = general.useragent. Right-click the preferences that are bold, one line at a time, and select Reset, Then restart Firefox
