The way your computer was behaving was almost like what it does with the add on FF has that is a Boss button, or Panic button. When clicked it takes you to your home page, or a page of your designation.
You didn't by any chance have that add on did you??
"Sort of" is such a harmless thing to say. "Sort of". It's just a filler. "Sort of" - It doesn't really mean anything. But after certain things, "sort of" means everything. Like after "I love you" or "You're going to live" or "It's a boy".
