Not sure about the first two points, but on the third, and if I’m understanding you correctly, there is an option in ‘Settings’ under ‘Appearance’ to use a wide location bar.
Thank you! Hope there is a fix for the menu and hopefully the popping to the next screen. Not happened since I got home but only have had the browser up for a few minutes.
So I think I know where this popping to the other monitor behavior is coming from. If I use my Middle Mouse/Scroll button/wheel it will do that. So this is no acceptable to me. Even if I use the middle button to close a tab sometimes the browser will pop over to the other monitor and NOT close the tab. Very annoying!
