I’m using 50.0a2 Developer Edition( also used Nightly 51…)
The browser console does not give any indication about undefined variables.
I’d need to wrap using:
try{
fun();
}catch(e){
console.log(e);
}
To get to know about undefined variables.
Though I could see a related warning in the Background page console for the reason of why a variable defined in the file could not be loaded( please see the photo)
Can someone tell me the reason?
