Uncaught TypeError: Cannot read property 'addEventListener' of null chrome-extension

For a few hours when I debug my application on my browser I have this error appears:

Uncaught TypeError: Cannot read property 'addEventListener' of null chrome-extension://fommidcneendjonelhhhkmoekeicedej/scripts/optionsToggle.js

I open the link in a new tab in order to have the optionToggle.js code, wich is:

// Javascript for welcome page buttons
function showFirstTime() {
    $('#firstTimeSection').toggle('slow');
    $('#updatesSection').hide();
}
function showUpdate() {
    $('#updatesSection').toggle('slow');
    $('#firstTimeSection').hide();
}

document.getElementById('firstTimeBtn').addEventListener('click',showFirstTime);
document.getElementById('oldTimerBtn').addEventListener('click',showUpdate);

The line where the error occured is the penultimate line:

document.getElementById('firstTimeBtn').addEventListener('click',showFirstTime);

The only thing I made today is to update the chrome version.

Someone know what this error really means and how to solve her?

Thank You in advance.

The real error here is that you are trying to add an event listener to a DOM object that doesn't exist on the page, which is why the error states you can't set that property on null.

Well it's an extension, you have an extension that is running that script. Go to chrome:extensions in your browser, turn on developer mode and match the id: fommidcneendjonelhhhkmoekeicedej
