Hi, I googled MapQuest yesterday, and clicked on what I thought was MapQuest without checking that it was. It gave me a screen that said if you download this you will be able to get all of your directions and maps etc. So I clicked on yes download. My computer warned me that it didn't seem safe, but I figured it's MapQuest it's fine. When I still wasn't able to get to where my directions were, I finally looked at the top bar, and saw that it wasn't MapQuest, that I had been hijacked to another website. So I'm wondering what to do. I went to an Apple store, but the guy that I talked to didn't know anything about Firefox. He did take me through looking at applications, and there was no new application that has been added. But I don't know if there are any add-ons that have been added etc. I'm wondering how to check it, or if I should reinstall Firefox? And then another question which is more minor is that it also changed my search engine from Google to Ask, and I want to change it back to Google but don't know how to. Thank you! Kathleen
