When I try to download a add on I get the message that a older version of Firefox is on my computer and I need to upgrade to Firefox4. I have just done that 3 times.

Your UserAgent is screwed up by something you installed in the past, telling websites that you have Firefox 3.6.15 installed - Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15 GTB7.0 ( .NET CLR 3.5.30729; .NET4.0C) FBSMTWB - you need to fix your UserAgent string.

Either I don't have a "location bar" or not the right one. Because when I enter about:config in either of my search bars I get the results of a google search. So now what do I do?

Thanks
