Comment (by cypherpunks):

 TB previously displayed a yellow bar warning after maximizing the window.

 From comment:22:ticket:7255:
 > "Maximizing Tor Browser can allow websites to determine information
 about your monitor size, which can be used to track you. We recommend you
 leave Tor Browser windows in their original default size. [OK]"

 It was disabled in #31598.

 Why not bring that back but have a letterboxing message? It could pop up
 once per New Identity if the letterbox border is displayed or is larger
 than the web content dimensions. It could have an internal preference
 count to display it once per New Identity up to 3 times, similar to what
 the yellow bar did.
