Is there a method to troubleshoot code that has been added through the firefox developer console terminal? For example, I added
document.onkeydown = function(event) {
// code logic for checking keys pressed
}
If only I could determine which .js file the javascript entered from the developer console is stored in, then I would be able to debug it. However, this has been a challenge for me so far.
To activate the debug console on Chrome, follow these steps:
document.onkeydown = function(event) {
console.log(event)
}
You will receive a function as the output.

If you double click on the function, a VM.js tab will appear. This tab contains the VM-generated code for this particular function, allowing you to set breakpoints as needed.
The debugger statement proved to be incredibly useful for me.
document.onkeydown= function(event){
debugger;
// Adding function logic here
}
By using the image below as a guide, you can easily set breakpoints in the debugger at key points in your code. https://i.sstatic.net/uw3uB.png
