Add-in shows status disconnected after upgrade to Firefox ESR 78.4.0-esr

I had the add-in for Firefox and the Alfred Workflow working just fine but now I cannot get the add-in to connect to the workflow. I have removed the add-in and then added it back via the workflow and then used the Register Workflow with browser but I when I attempt to activate the add-in, it still shows that status of disconnected. I have tried closing Firefox after removing the add-in and then restarting it before I re-install the add-in. I still get disconnected.
