Close Browser without Prompt

Question

Is it possible to close browsers, using JavaScript, PHP, or HTML without a prompt?

I was using this answer: How can I close a browser window without receiving the "Do you want to close this window" prompt?

I was using Internet Explorer but it has since been updated to version 10 (soon to be updated to 11) and this exploit does not work.

If there is a solution in a different (but updated) browser, that could work as well.

Answer 1

• HTML can't do anything programatic. It's just markup.
• PHP can only do programatic stuff at your server, not the browser, so no solution there either.
• Finally, you cannot do it in JS either (unless it's a window opened by a script).

Imagine visiting a web site that closed your browser and you lost all of your open tabs.
