Recording using Firefox - slow response

ART Version 5.40.4.2127, FireFox 80.0 (64-bit)

I am attempting to record steps for ServiceManager using the Firefox browser.  The response time in the recorder is very slow, taking minutes to record one step.  Without the recorder on, the response from SM is fast.  These same steps in Chrome/IE, when recording, is very good.  Issue only occurs in Firefox.
