How to increase number of Call Stack entries in Google Chrome Developer Tools (or Firefox Firebug)? I am getting a Javascript error in a third party control\'s Javascript. A

I don't think there's a limit on call stack size*). Usually a stack trace that seems to come out of nowhere results from either

• an event listener
• a timeout (window.setTimeout)
• an interval (window.setInterval)
• some script loading after page has loaded (possibly iframe)

_{*) Of course, technically there certainly is some limit, but I gues it's practically irrelevant. Probably longint or something.}

edit: From Firebug source code:

    if (trace.frames.length > 100)  // TODO in the loop above
    {
        var originalLength = trace.frames.length;
        trace.frames.splice(50, originalLength - 100);
        var excuse = "(eliding "+(originalLength - 100)+" frames)";

        trace.frames[50] = new StackFrame.StackFrame({href: excuse}, 0, excuse,
            [], null, null, context);
     }

So Firebug will always show the first 50 and the last 50 items ("frames") of the call stack.
