Save a system restore point before you install this. It wrote over MS Edge and wipe out all my favorites. My last restore point was 5 days ago and I lost everything I did.
No body or is it just me being stupid?
I doubt an accidental oversight should be defined as stupidity. As a rule, before MS updates, and installing software, one should create a restore point.
I keep identical favorites and bookmarks in my Chrome browser and Edge. When (before) I installed the new Edge, I made a restore point. After installing, I had to import my bookmarks, etc. from Chrome browser via the new Edge settings.
