I write web-based software. Every day.
I have made every browser crash and become completely non-responsive, many times over. Chrome. Firefox. Opera. All of them.
Now, this is mostly through JavaScript, when I do something stupid by manipulating the DOM the wrong way or some other funny thing. I fix it and keep going. Because breaking the browser is bad.
Want to report it to the vendor? Great. Fine. Making a website dedicated to the crash? Waaaay too much time on your hands.
