OK, So my sisters are pretty much insecure bitches, They blame me for the computer being slow because I install "stuff".
So they have this thought in their minds that it's firefox making the computer slow, and they wanted me to uninstall it, I never did, So they Uninstalled it while I was sleeping.
So I installed it again just now, But for some reason, Firefox won't start anymore, I've installed it 3 times and It still wouldn't work, Can someone tell me what I can do to fix it?
