Thunderbird pats itself on the back for not loading external content and protecting your privacy, but at the same time has a bright yellow notification bar tempting you constantly to do exactly that.

There is a description of how to make that notification bar go away in Windows here. They want you to create a file called userChrome.css and add the following to it:

#mail-notification-top{ display: none; } 

I'm using Thunderbird 78 and Debian 10 and did a find search in my user folder and found .themes/CBlue/cinnamon/userChrome.css and added that css to it, saved and rebooted, but the notification in thunderbird is still there. Any ideas how to make it go away?
