Question

What is the equivalent of pressing Ctrl+C in console, for Chrome and Firefox? While implementing various algorithms I often write some buggy (while) loop, in Javascript, that doesn’t exit, makes the browser freeze. Reloading doesn’t work, clicking little X for closing the tab doesn’t do anything, and in a while (literally) I’m outta memory, system is swapping, and I’m leaving for a coffee break.

Answer 1

There is no such thing as a Ctrl + C for JavaScript. The browsers that executes JavaScript are usually protective of themselves. If any JavaScript hangs, they’ll throw a dialog asking if the user wants to stop the JavaScript.

The timeout duration can usually be found in the browser’s settings. You can find how to do it for FireFox here: http://kb.mozillazine.org/Dom.max_script_run_time
