write to text file w/o using IE

Is there any possibility to write a text file using Chrome/FF? On the other words, writing a text file w/o using ActiveX. Thank you.

This is basically the code that works if I'm using IE.

var fso1 = new ActiveXObject("Scripting.FileSystemObject");
var tf1 = fso1.CreateTextFile("c:\\PassFail.csv", true);

ActiveXObject

This code relies on Internet Explorer. Writing text files to client machines via javascript is really a security breach and is not acceptable. If developers could write code to save files onto your computer, we would be in serious trouble. The most you can write is a cookie :)

I heard there is something called XMLHttpRequest that is compatible to all browsers. What does that actually do? Is there something to do with Javascript? Thank you.
