Is there a way to temporary bypass updates warnings for the sake of other people's privacy?

Hello, So, I got the "Restart to keep using Firefox message" while working to make sure that certain HIPPA protected data. I cannot close out of the browser because I am in an incognito window. Is there a way to pause the message or can I only prevent it by disabling automatic updates? P.S. So I work in the very sensitive part of Data Engineering e911 that deals with medical patient reports that given ONLY to the doctor at the hospital when the fire department drops you off at a Hospital. Because of extremely sensitive nature some of the specific report fields, I am not longer legally allowed (by HIPPA as old as the law is) to use browsers like chrome. So, I have to use browser like Firefox that are still in compliance. I want Firefox to update, but I want to choose when it updates (on the first weekend when there is a national fire or storm disaster happening... which technically will be this first Saturday since the update on the 15th).
