My own solution (at least temporarily) to this situation is as follows. I've been an Opera user since the late 90's and I'm not about to completely abandon Opera for another browser (i.e. Vivaldi, Chrome, Firefox, Edge) regardless of the benefits other browsers bring AS well as the fact that the Opera browser is now Chinese-owned. I will continue to use it for everyday browsing with two exceptions: buying and banking. I'm using the Avast Safe Zone browser for both since it essentially sandboxes the browser when doing either. This means that 95% of what I do online is with Opera and 10% with Avast. I suppose you could do the same with Bitdefender's Safe Pay feature as well.
I second the smooth scrolling request to be an option in the settings menu. I set the mouse wheel to scroll many lines at a time to go through large documents and without smooth scrolling its hard to gauge where I'm at. It was one of the first things which I was looking for when I tried the new Opera.
