Interestingly I've had the same experience with firefox, I keep it installed as a fallback if something isn't working in chrome but every time I (infrequently) use it I have to dismiss several popups about new features and how to switch to it as my primary browser/import history etc.
I think I saw this too with firefox. My memory is a little hazy on this detail, but the _critical_ difference with firefox is that ctrl+t let me open a new tab and leave the sync-a-nag alone. Edge did not allow that, and I actually hat to wait while it was "Working on it".
This resonates so hard. I really wish that SW stop assuming that if they are just installed, then the user is a complete ignoramus who needs to be educated and onboarded. I (for reasons) frequently install OSes from scratch and all the boilerplate is so tedious.
