Uncaught ReferenceError: stopme is not defined (anonymous function)

Question

I keep seeing this non breaking exception in my console:

Uncaught ReferenceError: stopme is not defined

(anonymous function)

There is no variable called stopme being called in any of my files, did a full search in console. What I have are multiple:

setInterval(function() {
  updateMetrics();
}, 1000);

calls in my code, whenever one of them fails, this shows up in console. I also don't know if this is the default behavior but I also noticed every time I set a new interval using:

var intervalId = setInterval(function() {}, 1000);

that intervalId is non sequential as in:console.log(intervalId) the result is 1, 4, 9, 14. I am manually calling the code above from console to see why my intervalIds are auto incrementing.

This is the full stack trace:

Uncaught ReferenceError: stopme is not defined
(anonymous function)

Additional libraries:

bootstrap.js
d3.v3.js
ember.js
handlebars.js
jquery-1.9.1.js
jquery.jsPlumb.js
jquery.timeago.js
require.js
string.min.js

Error shows up only on Chrome, not in Firefox. My Chrome build is: Version 29.0.1547.57

I tracked this to my "Webpage Screenshot Capture" extension. Sucks because it's a great extension for capturing full height web pages. Can anyone recommend another?
