Yes, Griff is right. Here a Tip/Trick in javascript to handle that thing but it has disadvantages(If you refresh that page the same handle will execute[which you want only for browser X close event]) so you decide.

How to detect browser close when browser [X] is clicked?[^]

Nice reply, using jQuery makes this nice and simple - my 5

Yeah, you can find the solution in jQuery in my Tip/Trick. I don't know jQuery :(
Thank you again Espen

AFAIK, there is no reliable way to do this: It may be possible in Javascript on Firefox (the descriptions I have seen are vague, and seem to be version dependent, using various tricks) but nothing exists that works for all browsers.

And for a good reason. What do you think malicious sites would do with that?

Find another way to do what you are trying that does not involve detecting browser close: it will never be reliable, as the user can just pull teh mains lead out of the back of his PC...
