So, a friend of mine was having trouble with IE10, so I recommended that he download Firefox. He liked it, as it was quite fast. However, apparently after I left his house, he and his Mom were having trouble getting the computer to work, apparently going to a blue screen at startup. I haven't seen the screen myself. His Mom seems to think that it's because of Firefox that the computer isn't working at the moment. I'm positive that Firefox isn't a malicious program of any sort, and having used it for quite a while, it makes me wonder if with a computer such as theirs, a problem could occur simply from installing Firefox. Since you guys are a lot more tech-savvy than I am, I figured before just telling them that there's totally no way that Firefox could do that to one's computer, I'd ask you guys first.
So, is it possible for Firefox, after being downloaded and installed from Mozilla's website, to do something to your computer that would hinder the start-up in any way?
