I've been a Firefox user for at least 10 years. I recently installed Firefox on a new desktop PC, and the Firefox Privacy Notice tab popped up. "No worries," I thought, and read it and made my cookies choice. I didn't find anything about a separate "submit" or "Close" gadget, so I simply closed the tab. Now, every time I leave the Home page or open a new tab, the Firefox Privacy Notice keeps popping up. Please advise me how to close it for good.

I can't access/change printing instructions in PDFs because of a popup about highlighting PDFs. I tried Settings/Privacy & Security/PDF settings. I'm supposed to scroll down to "PDF Viewer" section but that's not available in the drop down menu.

Every time I open my laptop, I keep getting a banner which tells me firefox has notifications. But where are they? It appears in the upper right hand corner of my 2010 macbookpro and disappears without informing me as to where these notifications are. Anyone know where I can look? thanks

ps) none of the drop-down menu topics best describes this so I'm putting whatever in

On Windows, any notification coming from any Firefox extension, appears to be coming from the Firefox app. It would be cool to add a feature under (Privacy and Security --> Notification settings --> See attached image) that would allow to specify which extensions are allowed to send notifications and which are not.
