@jon Firefox to Vivaldi primary recent convert here.

Loads of reasons:
- not happy with Mozilla's direction lately
- don't like Chrome
- don't mind Safari but I don't want to be tied to Apple for my primary browser even though I'm a MacBook + iPhone user at the moment

Vivaldi almost wins by default at this point, but it has plenty to recommend it
- built in anti tracking / Adblock features feel "just right"
- works with my password manager Chrome extension
- workspaces
- generally nice to use
