a couple minutes to click through vivaldi's settings will turn off all the annoying stuff (similar to firefox, but firefox is quicker to 'set up'). i've never seen it re-enable things like microsoft loves to do.

vivaldi is what i use for a chromium-based browser when i need to check web client 'compatibility'; and i like that you can customize the toolbar (like you can in firefox).. i move the back-forward stuff to the right side of the address box, and add the separate search box (so suggestions can be enabled in it but off for searches in address bar).
