New windows open fullscreen
I use a laptop that I frequently connect to a large external monitor. When on the laptop, often my Firefox v69.0 (64-bit) browser windows are full-sized (not full-screen mode, but just taking up the entire desktop). When I plug in the external monitor, these windows migrate to the external monitor and are much smaller than full-screen. However, Firefox appears to continue to have these windows tagged as full-screen, as when I am on one of them, and open a new window using command-N, I get a full-scree (on the large external monitor) size window, rather than a window of the same size.
I don't think this is desired or intended behavior--is there a way to override it or submit a bug report?
Thanks
