As mentioned in the title, my extension function changed from the original default_popup to injecting iframe. However, I found a problem. When the web page is opened for a long time, my action icon will not respond no matter how I press it, and I cannot monitor it. Any error messages, been bothering me for a week or so, please help me!

I’m currently trying to develop a chrome extension where it relys on an video element. When I try to access it I get hit with an error.
