Safari has started always opening windows way too large for my screen
Hello
I have long used my MacBook with external displays, one at home, another at work, and sometimes solo, with no external display. For a long time this was no problem, as it detected screen size and opened new windows sized accordingly. But lately, every time I open Safari, regardless of with an external display or not, and regardless of whether I have shutdown and restarted or not, it ALWAYS opens new windows that are way, way too large for whatever screen I am using.
This has become very annoying, and time consuming as I am constantly resizing windows from beyond the confines of my screen.
Any ideas what causes this, and how to fix it?
Thank you
MacBook, macOS 10.15
